Best Ornn Build & Guide (2026) — League of Legends

Ornn is League of Legends' fire-breathing demigod of the forge — a vanguard tank who crafts items anywhere on the map, upgrades his teammates' items into powerful Masterwork versions, breathes fire to apply Brittle for devastating crowd control follow-ups, charges through terrain to knock up enemies, and summons a massive lava elemental with Call of the Forge God to engage teamfights from enormous range. Ornn is played primarily in the top lane with a 52.25% win rate on Patch 16.6 in Emerald+ on u.gg (S+ tier, ranked 4/63 top laners) and a 53.49% win rate on LoLalytics (S- tier, ranked 9/103 top laners), functioning as one of the strongest teamfight tanks in the game who provides massive engagement, crowd control chains, and permanent item upgrades that give his entire team a gold advantage. Whether you are a top lane main looking for a champion who dominates teamfights with game-changing ultimates, a team-oriented player who wants to provide permanent item upgrades to teammates, or a climbing player who wants a high win rate tank that scales into every stage of the game, this guide covers everything you need to dominate with Ornn in 2026.

Ornn Overview

Ornn operates as a vanguard tank whose power comes from his unique forge mechanic, devastating crowd control chains, and the ability to upgrade his teammates' items into Masterwork versions worth approximately 1000 extra gold each. He is currently played primarily in the top lane (52.25% win rate on u.gg Emerald+, 53.49% on LoLalytics). His pick rate sits around 5.5-5.8% with a 1.1% ban rate, reflecting his status as a consistently strong top lane tank whose value comes from teamfight engagement, Brittle crowd control amplification, and permanent gold advantages through Masterwork upgrades.

Unlike carry top laners who aim to win lane and snowball, Ornn's identity revolves around scaling into a teamfight monster who provides more value than any other tank in the game — Living Forge lets him stay in lane indefinitely by purchasing items without recalling, Temper amplifies his bonus stats by up to 30%, Master Craftsman upgrades five Legendary items across his team for approximately 5000 gold worth of free stats, and Call of the Forge God engages teamfights from over 2500 range with a massive knockup that can hit the entire enemy team. This makes Ornn a champion who provides permanent, compounding advantages that only grow stronger as the game progresses.

Living Forge (Passive) allows Ornn to spend gold to forge non-consumable items anywhere on the map with a 4-second channel, interrupted by champion or turret damage. Living Forge means Ornn never needs to recall for items — he can stay in lane permanently, maintaining wave pressure and experience while his opponent must recall to spend gold. This creates a significant laning advantage where Ornn can shove waves, force his opponent to recall, and then forge his own items while maintaining lane presence and denying the opponent CS.

Master Craftsman (Passive) activates at level 13, automatically upgrading Ornn's first eligible Legendary item into its Masterwork variant. At levels 14, 15, 16, and 17, Ornn can upgrade one allied champion's Legendary item within 600 units, for a total of 5 Masterwork upgrades (1 self + 4 allies, once per ally per game). Each Masterwork upgrade grants approximately 1000 gold worth of bonus stats distributed among the item's upgradeable stats. This passive is what makes Ornn uniquely valuable — by level 17, Ornn has generated approximately 5000 gold worth of free stats across his team, an advantage that no other champion in the game can provide.

Temper (Passive) causes Ornn to increase his bonus armor, bonus magic resistance, and bonus health by 10% from all sources, further increased by 4% each time he upgrades a Legendary item into a Masterwork item, for a maximum of 30% increase to each stat after all 5 upgrades. Temper makes Ornn significantly tankier than his raw item stats would suggest — at 30% amplification, every armor, MR, and health item Ornn builds is 30% more gold-efficient on him than on any other champion.

Brittle (Passive Mechanic) is applied by Bellows Breath's final gout of flame and both passes of Call of the Forge God. Brittle lasts 3 seconds. Basic attacks on Brittle targets apply a knockback effect and consume the Brittle mark. Immobilizing effects on Brittle targets increase the immobilization duration by 30% and deal bonus magic damage equal to 10% – 18.94% (based on Ornn's level) of the target's maximum health, with a monster damage cap of 200-500 (based on Bellows Breath rank). Brittle is what makes Ornn's crowd control chains devastating — a Brittle target hit by Searing Charge's knockup is knocked up for 1.625 seconds instead of 1.25 and takes massive bonus max health damage.

Volcanic Rupture (Q) causes Ornn to slam the ground, sending a fissure in the target direction that deals 20 / 45 / 70 / 95 / 120 (+110% total AD) physical damage and slows enemies by 40% for 2 seconds. After 1.125 seconds, a magma pillar erupts at the fissure's end, lasting 4 seconds as impassable terrain. Volcanic Rupture has a range of 750, a width of 130, a missile speed of 1800, a cooldown of 9 / 8.5 / 8 / 7.5 / 7 seconds, and costs 45 mana at all ranks. The magma pillar is critical because it creates terrain that Ornn can charge into with Searing Charge for an area-of-effect knockup, forming Ornn's bread-and-butter Q-E combo.

Bellows Breath (W) causes Ornn to march forward unstoppably over 0.75 seconds, breathing fire in a cone that deals 12 / 13 / 14 / 15 / 16% of the target's maximum health as magic damage over 5 ticks, with a minimum of 80 / 130 / 180 / 230 / 280 damage against minions and a monster damage cap of 260 / 320 / 380 / 440 / 500. The final gout of flame applies Brittle to enemies hit for 3 seconds. Bellows Breath has a range of 500/560, an effect radius of 175, a cooldown of 12 / 11.5 / 11 / 10.5 / 10 seconds, and costs 45 / 50 / 55 / 60 / 65 mana. The unstoppable effect during the march makes Ornn immune to displacement during Bellows Breath, allowing him to breathe fire through crowd control abilities. The percent max health damage makes Ornn's trading powerful against both tanks and bruisers in lane.

Searing Charge (E) causes Ornn to charge forward, dealing 80 / 125 / 170 / 215 / 260 (+40% bonus armor) (+40% bonus MR) physical damage to enemies he passes through. If Ornn collides with terrain, he creates a shockwave that deals the same damage and knocks up enemies for 1.25 seconds. Searing Charge has a range of 800, an effect radius of 360, a speed of 1600, a cooldown of 14 / 13.5 / 13 / 12.5 / 12 seconds, and costs 35 / 40 / 45 / 50 / 55 mana. Searing Charge's damage scaling with bonus armor and magic resistance makes it deal increasingly significant damage as Ornn builds tank items — at full build, the 40% bonus armor and 40% bonus MR scalings add substantial physical damage on top of the base values. The terrain collision knockup is Ornn's primary hard CC in lane, and destroying Volcanic Rupture's pillar or enemy-created terrain with the charge triggers the shockwave.

Call of the Forge God (R) causes Ornn to summon a massive lava elemental at maximum range (2550-3000 units) that stampedes toward him, dealing 125 / 175 / 225 (+20% AP) magic damage, slowing enemies by 40 / 50 / 60% for 2 seconds, and applying Brittle to enemies it passes through. Ornn can recast the ability after a minimum 1.25-second delay to dash forward — if he collides with the elemental, it is redirected in the new direction, dealing 250 / 350 / 450 (+40% AP) magic damage, stunning enemies for 1 second (reduced to 0.5 seconds after the first champion hit), and applying Brittle again. Call of the Forge God has a cooldown of 140 / 120 / 100 seconds and costs 100 mana. Call of the Forge God is one of the longest-range engage ultimates in the game, capable of initiating fights from over 2500 units away. The double Brittle application means enemies hit by both passes take massive bonus max health damage when subsequently CC'd, and the slow-into-stun combination makes it extremely difficult for enemies to escape.

Strengths

• Call of the Forge God is one of the most powerful teamfight engagement tools in the game because it initiates from over 2500 range, deals 375/525/675 (+60% AP) total magic damage across both passes, slows by 40-60%, stuns for 1 second, and applies Brittle twice — a well-landed ultimate on 3-5 enemies sets up devastating follow-up crowd control where every subsequent immobilize deals 10-18.94% max health bonus damage and lasts 30% longer — The sheer range and width of the elemental makes it nearly impossible to dodge in chokepoints around Baron and Dragon pits
• Master Craftsman generates approximately 5000 gold worth of free stats across the team by upgrading 5 Legendary items into Masterwork versions, creating a permanent and compounding advantage that no other champion in the game can replicate — at full upgrades (level 17), Ornn's team effectively has a full item's worth of bonus stats distributed among their strongest items — Combined with Temper's 30% bonus stat amplification on Ornn himself, Ornn's team is systematically stronger in every stat than their opponents at equal gold
• Ornn's Living Forge passive means he never needs to recall for items, allowing him to maintain permanent lane presence while his opponent must leave lane to shop — this creates consistent CS and experience advantages, denies opponents tempo-based plays around item purchases, and lets Ornn stay in lane during critical early game windows when top laners typically need to recall — Ornn can shove a wave, forge an item component, and be ready for the next wave while his opponent is still walking back to lane
• Ornn's crowd control chain of Q pillar into E charge knockup (1.25 seconds, extended to 1.625 with Brittle), combined with W Brittle application and R engagement, creates one of the longest and most devastating CC chains of any tank — a full combo of R1 (Brittle + slow) into R2 (Brittle + stun) into W (Brittle) into Q-E (knockup on Brittle target) can lock down a target for several seconds while dealing massive percent max health damage — The Brittle mechanic also amplifies teammates' CC, making Ornn's value multiply with coordinated follow-up

Weaknesses

• Ornn has limited mobility and no escape tools, making him vulnerable to being kited by ranged top laners and stuck in unfavorable positions — his only gap-closer is Searing Charge, which requires terrain collision for the knockup and has a long 14-12 second cooldown, leaving Ornn with no tools to chase enemies or retreat from bad fights between ability rotations — Champions like Vayne, Quinn, and Kennen can abuse this immobility to poke Ornn freely in lane
• Ornn's damage output is relatively low compared to carry top laners, meaning he cannot solo-kill opponents without extended trades and multiple ability rotations — while Bellows Breath's percent max health damage is strong for trading, Ornn lacks the burst damage to finish kills without teammate follow-up or extended fights where he can cycle through multiple ability rotations — This means Ornn often needs to rely on his jungler for lane kills and cannot solo-carry games through damage alone
• Ornn's Bellows Breath roots him in place for 0.75 seconds during the fire-breathing animation, making him predictable and vulnerable to skillshot abilities and ganks — experienced opponents can bait out Bellows Breath and then punish the self-root with abilities that Ornn cannot dodge during the march — Champions like Darius, Fiora, and Camille can punish this predictable pattern with their own abilities
• Ornn's Master Craftsman upgrades do not activate until level 13 (self) and levels 14-17 (allies), meaning his unique team advantage does not materialize until the mid-to-late game — in games that are decided early, Ornn's passive provides no value, and his relatively weak early game damage means he can fall behind before his upgrades come online — Teams that draft early-game compositions can close out the game before Ornn's scaling advantage becomes relevant

Recommended Runes

Top Lane — Grasp of the Undying (Resolve)

The recommended rune page for Ornn top is Grasp of the Undying with approximately 53.57% win rate on LoLalytics Patch 16.6. Grasp synergizes with Ornn's melee trading pattern and permanent health stacking that benefits from Temper's bonus stat amplification.

• Grasp of the Undying — After 4 seconds in combat, your next basic attack deals bonus magic damage equal to 3.5% of your max health, heals you for 1.7% of your max health, and permanently increases your health by 7. Grasp of the Undying is ideal for Ornn because his melee trading pattern in top lane naturally procs Grasp during short trades, the permanent health stacking synergizes with Temper's bonus health amplification (10-30% increase to bonus health), and the sustain keeps Ornn healthy during the laning phase where he wants to stay in lane and forge items without recalling.
• Demolish — Charges a powerful attack against towers over 3 seconds while near them, dealing bonus physical damage based on your max health. Demolish synergizes with Ornn's high health pool and Temper-amplified bonus health, allowing him to chunk towers after winning trades or forcing opponents to recall. Since Ornn never needs to recall for items, he can capitalize on every window to damage towers.
• Conditioning — After 12 minutes, gain bonus armor and magic resistance, plus a percentage increase to both stats. Conditioning amplifies Ornn's mid-to-late game tankiness significantly because the percentage bonus stacks multiplicatively with Temper's bonus stat amplification, making Ornn extraordinarily tanky once Conditioning activates and his Masterwork upgrades come online.
• Overgrowth — Gain permanent bonus health for each nearby minion or monster death. Overgrowth provides permanent health scaling that benefits from Temper's bonus health amplification, making every stack worth 10-30% more on Ornn than on any other champion. Combined with Grasp stacking, Ornn accumulates a massive health pool over the course of the game.

Secondary — Inspiration

• Biscuit Delivery — Receive a Total Biscuit of Everlasting Will at intervals, restoring health and mana and permanently increasing maximum mana. Biscuit Delivery provides crucial mana sustain for Ornn's early laning phase, where his ability costs can strain his mana pool during extended trades and wave clear. The permanent mana increase also helps sustain his ability usage throughout the game.
• Magical Footwear — Receive free Slightly Magical Boots at 12 minutes (reduced by takedowns). Magical Footwear saves Ornn 300 gold on boots, which synergizes with his item-efficient playstyle — the gold savings compound with his already efficient forge passive and Temper stat amplification to give Ornn even more value per gold spent.

Stat Shards

• Adaptive Force — Extra AD increases damage on Volcanic Rupture and Searing Charge, improving Ornn's trading and wave clear during the early laning phase.
• Move Speed — Bonus movement speed helps Ornn close gaps for Bellows Breath trades and dodge skillshots in lane, compensating for his lack of mobility.
• Health Scaling — Bonus health scaling outperforms flat health after level 7 and synergizes with Temper's bonus health amplification and Grasp of the Undying's max health scaling.

Recommended Item Build

Based on data from ranked Ornn matches tracked across multiple stat sites on Patch 16.6, here are the highest winrate build paths.

Top Lane Build

#### Early Game (0-10 min)

• Doran's Shield — Grants health and passive health regeneration, with bonus regeneration after taking damage from enemy champions. Doran's Shield is the standard starting item for Ornn because the health regeneration sustains him through poke and short trades, and the bonus regeneration after taking champion damage helps him survive aggressive matchups. Since Ornn wants to stay in lane as long as possible to leverage Living Forge, Doran's Shield's sustain is more valuable than Doran's Ring or Blade.
• Health Potion — A Health Potion provides additional sustain for early trades and poke, keeping Ornn healthy enough to farm and trade during the first few levels before he can forge his first item component.

#### Core Build (10-20 min)

• Sunfire Aegis — Grants health, armor, magic resistance, ability haste, and a passive that deals persistent area-of-effect magic damage to nearby enemies. Sunfire Aegis is Ornn's optimal first item with a 52.4% win rate because the Immolate passive adds consistent area damage during trades and teamfights that synergizes with Ornn's melee-range fighting pattern. The combined defensive stats benefit from Temper's amplification, and the ability haste reduces Ornn's long cooldowns for more frequent ability rotations.
• Plated Steelcaps — Grants armor and reduces incoming basic attack damage. Plated Steelcaps are the standard boot choice for Ornn because most top lane matchups involve auto-attack-heavy champions, and the damage reduction stacks with Ornn's armor from Temper amplification. Against heavy AP compositions, Mercury's Treads provide tenacity and magic resistance instead.
• Thornmail — Grants armor, health, and applies Grievous Wounds to enemies who attack you. Thornmail is Ornn's core second item because it provides anti-heal that Ornn applies passively through being attacked, armor that scales with Temper and Searing Charge's 40% bonus armor ratio, and health that Temper amplifies. Against teams with healing, Thornmail's Grievous Wounds are essential.

#### Late Game (25+ min)

• Jak'Sho, The Protean — Grants health, armor, magic resistance, and a passive that increases resistances while in combat, then releases a burst of damage. Jak'Sho is Ornn's highest win rate late game item at 62.28% because the ramping resistances during extended teamfights stack with Temper's 30% amplification, making Ornn astronomically tanky the longer a fight continues. The burst damage passive adds threat that enemies cannot ignore.
• Kaenic Rookern — Grants health, magic resistance, and a passive magic damage shield. Kaenic Rookern provides critical magic resistance against AP-heavy compositions, and the magic damage shield synergizes with Ornn's desire to frontline in teamfights where he absorbs massive amounts of magic damage while setting up CC chains.
• Randuin's Omen — Grants armor, health, and an active that slows nearby enemies, with passives that reduce critical strike and attack damage. Randuin's Omen is essential against crit-heavy AD compositions because the critical strike damage reduction stacks with Ornn's already massive armor from Temper amplification, and the active slow helps Ornn stick to targets after engaging.

Ability Priority

Top Lane: W > E > Q (R at 6, 11, 16)

1. Bellows Breath (W) — Max first. Levels at 1, 3, 5, 7, 9. Each rank increases the percent max health damage from 12% to 16% and the minimum minion damage from 80 to 280, while cooldown decreases from 12 to 10 seconds. Maxing W first is essential because the percent max health damage is Ornn's strongest trading tool in lane — at 16% max health damage, a single Bellows Breath chunks bruisers and tanks significantly. The Brittle application on the final tick enables devastating follow-up CC, and the damage is effective regardless of the enemy's build.
2. Call of the Forge God (R) — Level at 6, 11, and 16. Each rank increases first-pass damage from 125 to 225 and recast damage from 250 to 450, while cooldown decreases from 140 to 100 seconds and the slow increases from 40% to 60%. Level 6 is a massive power spike because Call of the Forge God provides long-range engagement and teamfight presence that Ornn previously lacks.
3. Searing Charge (E) — Max second. Levels at 2, 8, 10, 12, 13. Each rank increases base damage from 80 to 260, while cooldown decreases from 14 to 12 seconds. Maxing E second provides increasing damage that scales with bonus armor and MR (40% each), meaning each point in E becomes more valuable as Ornn builds tank items. The knockup duration remains 1.25 seconds at all ranks.
4. Volcanic Rupture (Q) — Max last. Levels at 4, 14, 15, 17, 18. Each rank increases damage from 20 to 120 and reduces cooldown from 9 to 7 seconds. While the pillar terrain is valuable for E combos, Q's damage scaling is the lowest in Ornn's kit and the mana cost stays flat at 45, so it benefits least from additional ranks compared to W and E.

Summoner Spells

• Flash — Flash is essential for Ornn because he has limited mobility outside of Searing Charge, and Flash provides instant repositioning for clutch Call of the Forge God redirections, surprise E-Flash knockups over terrain, and escape from lethal situations. Flash into E against a wall is a critical engage tool that catches opponents off guard.
• Teleport — Teleport is the standard secondary summoner spell for Ornn top lane because it allows him to join teamfights across the map after pushing waves, return to lane quickly after forced recalls, and maintain the permanent lane presence that Living Forge enables. Teleport's global pressure synergizes with Ornn's teamfight-focused playstyle.

Playstyle Tips

Early Game / Laning Phase (0-14 min)

Ornn's early game is about farming safely, trading with Bellows Breath and Grasp procs, and leveraging Living Forge to build item advantages without recalling.

Start Bellows Breath at level 1 for percent max health trading damage and Brittle application. Take Searing Charge at level 2 for the Q-less knockup against walls or the W-into-E trade combo. Take Volcanic Rupture at level 4 for the full Q-E pillar combo. In early levels, focus on short trades where you walk up, W the enemy for Brittle application and percent max health damage, then auto attack to proc both Grasp and Brittle's knockback for a powerful short trade that you always win.

Living Forge is Ornn's most underutilized advantage in the early game. When you have enough gold for an item component, shove the wave and forge it while the wave bounces back. Your opponent must recall to spend their gold, losing CS and experience, while you maintain full lane presence. This compounding advantage means Ornn often has a 10-20 CS lead by 10 minutes simply through lane presence.

Ornn's Q-E combo is his bread-and-butter in lane: cast Q to send a fissure that creates a pillar, then E toward the pillar to collide with it and create a knockup shockwave. Time the E dash to arrive at the pillar's location as it erupts (1.125 seconds after Q cast) for maximum reliability. In gank setups, the Q slow into E knockup provides strong CC for your jungler to follow up.

Mid Game & Teamfighting (14-25 min)

Mid-game Ornn with Sunfire Aegis and Thornmail is a teamfight-dominant tank whose Call of the Forge God engagement and Masterwork upgrades create overwhelming advantages in grouped fights around objectives.

Level 13 is a critical power spike — Ornn's first Masterwork upgrade activates automatically, and subsequent levels (14-17) allow him to upgrade allies' items. Prioritize upgrading your ADC's and mid laner's items first, as the damage-oriented Masterwork upgrades provide the highest impact. Communicate with your team to stand near you after leveling up so you can upgrade their items immediately.

In teamfights, Ornn has two primary engagement patterns. The first is the long-range R1 into R2 redirect combo: cast Call of the Forge God to summon the elemental from max range, let it pass through the enemy team (applying Brittle and slowing), then recast to dash forward and redirect the elemental back through them for the stun and second Brittle application. Follow up with W for a third Brittle application and Q-E for the pillar knockup on Brittle targets. The second pattern is flanking with E into terrain for a surprise knockup, then W for Brittle, and R to engage the rest of the fight.

Never engage with R unless you have follow-up from your team. Ornn's crowd control chain is devastating but requires teammates to capitalize on the CC duration and Brittle-amplified damage. Communicate your ultimate timings and target selection before fights begin.

Late Game (25+ min)

Late-game Ornn with full items and all Masterwork upgrades is a nearly unkillable frontline whose 30% Temper amplification, Conditioning scaling, and Jak'Sho ramping resistances create a wall of stats that enemy teams struggle to break through, while his team benefits from 5000 gold worth of free Masterwork stats.

In late-game teamfights, Ornn's value is unmatched among tanks. His Call of the Forge God can initiate Baron and Elder Dragon fights from fog of war, his Brittle application on the entire enemy team sets up devastating follow-up CC, and his own tankiness allows him to absorb the enemy team's cooldowns while his carries deal damage freely. Position in front of your team, look for multi-person R engages, and peel for your carries with Q-E knockups and W Brittle applications if enemies dive past you.

Avoid split-pushing in the late game — Ornn's value is in grouped teamfights where his CC chains and Masterwork advantage are maximized. Stay with your team for objective fights and use Living Forge to maintain full-item status without ever needing to leave the group to recall.

Matchups

Top Lane

#### Favorable

• Akali — Ornn wins approximately 60.2% against Akali in top lane. Akali's assassin kit struggles against Ornn's innate tankiness and Bellows Breath's percent max health damage that Akali cannot mitigate with her shroud. Ornn can trade into Akali with W during her Twilight Shroud since Bellows Breath hits the entire cone regardless of stealth, and his CC chain locks Akali down after she uses her dashes. Akali cannot burst through Ornn's health pool, and Ornn outscales her in teamfight value.
• Smolder — Ornn wins approximately 59.6% against Smolder in top lane. Smolder is a scaling champion who needs to farm stacks peacefully, but Ornn punishes him with Bellows Breath trades that deal percent max health damage Smolder cannot sustain through. Ornn's Q-E knockup catches Smolder's immobile frame easily, and Call of the Forge God can engage on Smolder from ranges he cannot escape. Ornn outscales Smolder in teamfight utility through Masterwork upgrades.
• Maokai — Ornn wins approximately 59.5% against Maokai in top lane. Maokai is a fellow tank who wants to sustain through lane, but Ornn's percent max health damage from Bellows Breath shreds through Maokai's health pool regardless of his passive healing. Ornn's Brittle mechanic amplifies his CC chain duration beyond what Maokai can match, and Ornn's Masterwork upgrades provide more team value than Maokai's engage tools in the late game.

#### Even

• Aatrox — Aatrox is a skill matchup where both champions trade effectively in extended fights. Aatrox's Darkin Blade sweet spots deal massive damage, but Ornn can use Bellows Breath's unstoppable march to absorb the knockups and trade back with percent max health damage. Ornn wins short trades with W-auto Brittle procs, while Aatrox wins extended fights where he can land multiple Q sweet spots and heal with Goredrinker. The matchup favors whoever manages their cooldowns better.
• Garen — Garen is an even matchup where simplicity meets crowd control. Garen's Decisive Strike silence prevents Ornn from using abilities during trades, and Demacian Justice execute threatens Ornn at low health. However, Ornn's Bellows Breath trades effectively into Garen's Courage cooldown, and Ornn's CC chain in teamfights provides far more value than Garen's single-target kit. The lane is relatively passive with both champions farming for teamfights.
• Mordekaiser — Mordekaiser is an even matchup where sustained damage meets crowd control. Mordekaiser's Realm of Death isolates Ornn from his team, negating his teamfight value, but Ornn can trade effectively with Bellows Breath's percent max health damage during Mordekaiser's passive proc windows. In teamfights, Mordekaiser wants to ult Ornn's carry while Ornn wants to engage on the enemy backline — the matchup depends on which champion's team capitalizes on their utility better.

#### Unfavorable

• Singed — Ornn wins only approximately 44.7% against Singed in top lane. Singed's proxy farming pattern completely bypasses Ornn's trading strengths — Ornn cannot engage on Singed with his slow combo when Singed is running behind Ornn's tower. Singed's Fling disrupts Ornn's E charge, his Poison Trail dots Ornn down during extended chases, and Singed's Mega Adhesive grounds Ornn to prevent Searing Charge entirely. Singed outroams Ornn and creates map pressure that Ornn's immobile kit cannot answer.
• Zac — Ornn wins only approximately 45.3% against Zac in top lane. Zac's sustained percent max health damage trades evenly with Ornn's Bellows Breath, but Zac's passive healing from picking up blobs gives him sustain advantages in extended trades. Zac's Elastic Slingshot engage range matches Call of the Forge God, and Zac's Let's Bounce provides comparable teamfight disruption. Zac effectively matches everything Ornn does while outsustaining him in lane.
• Cassiopeia — Ornn wins only approximately 47.5% against Cassiopeia in top lane. Cassiopeia's sustained DPS with Twin Fang shreds through Ornn's health pool faster than he can trade back, and her Miasma grounding zone prevents Ornn from using Searing Charge to engage or escape. Cassiopeia's Petrifying Gaze counters Ornn's Bellows Breath march by forcing him to either face her and get stunned or turn away and waste W's damage. Cassiopeia outscales Ornn in raw damage output.

Recent Patch Changes

Patch 25.23 (November 2025) — Buff

Riot buffed Ornn's monster damage capabilities to expand his viability into the jungle role.

• Living Forge (Passive): Brittle monster damage cap increased to 260-500 (based on Bellows Breath rank) from 250 at all levels.
• Bellows Breath (W): Total monster damage cap increased to 260/320/380/440/500 from 155/180/205/230/255. This buff nearly doubled Ornn's jungle clear damage against monsters, making jungle Ornn a viable off-meta option while also buffing his Rift Herald and Baron damage when played in top lane.

No major balance changes have been made to Ornn in 2026 patches — his strong 52-53% win rate reflects the favorable state of tank itemization in Season 16 rather than direct champion buffs.
