Illaoi is a champion in League of Legends played exclusively in the top lane, classified as a Juggernaut (legacy class: Fighter, Tank). The Kraken Priestess uses Mana (350 – 1333.25 at max level) and deals Physical damage. Illaoi was released on November 24, 2015, and was last changed in patch V25.18. With Black Cleaver into Iceborn Gauntlet as her core build in the current meta, Illaoi is a lane bully who becomes an absolute monster in teamfights around her tentacle zone.

💡 Unique Mechanic: Illaoi’s entire identity revolves around tentacles. They spawn automatically near terrain, attack when commanded by her abilities, and heal her for 5% missing health every time they hit a champion. The more tentacles around you, the stronger you are. Fighting Illaoi inside her tentacle zone is practically suicide – and that’s exactly how she wants you to play.
🧊 Passive: Prophet of an Elder God
INNATE: Periodically, Illaoi spawns a Tentacle on the nearest terrain, if no other Tentacle is around it. Tentacles fully spawn after a 2-second delay and are untargetable in the meantime. Static Cooldown: 18 – 5.71 seconds (based on level). Effect Radius: 1000.
Tentacles are commanded to attack by Illaoi’s abilities, dealing 9 – 180 (based on level) (+ 110% AD) (+ 40% AP) physical damage to all enemies struck, increased by 0% – 30% (based on Q rank). Each enemy individually reduces slam damage by 50% for every slam in the last 0.66 seconds, capped at 75% less damage.
Each Tentacle also heals Illaoi for 5% of her missing health if it hits at least one enemy champion. This healing is the reason Illaoi becomes nearly unkillable in multi-tentacle zones – every slam on champions is a massive heal.
🦫 Q: Tentacle Smash
Cost: 40 / 45 / 50 / 55 / 60 Mana | Cooldown: 10 / 9 / 8 / 7 / 6 seconds | Cast Time: 0.75 | Range: ~803
PASSIVE: Tentacle damage is increased by 10 / 15 / 20 / 25 / 30%.
ACTIVE: Illaoi slams down a Tentacle in the target direction. This is her primary poke and wave clear tool. The tentacle slam hits in a line, dealing full passive tentacle damage with the Q passive bonus. Illaoi reveals herself during the cast if there is an enemy champion nearby.
💡 Pro Tip: Q’s passive damage increase applies to ALL tentacle slams – not just Q itself. This means maxing Q first increases the damage of W-commanded tentacles, R tentacles, and E vessel tentacles too. Q max is essentially a global tentacle damage steroid.
👊 W: Harsh Lesson
Cost: 30 Mana | Cooldown: 4 seconds | Cast Time: NONE
ACTIVE: Illaoi empowers her next basic attack within 6 seconds to gain 225 bonus range and cause her to leap to the target if they are beyond her normal basic attack range. The attack deals additional physical damage and commands all Tentacles in range to attack the target. Harsh Lesson resets Illaoi’s basic attack timer and can be activated during other abilities.
| Parameter | Value |
| Additional Damage | 3/3.5/4/4.5/5% (+3.5% per 100 AD) max HP |
| Minimum Damage | 20/30/40/50/60 |
| Non-Champion Cap | 300 |
➡️ Key Mechanic: W is your tentacle commander. Every time you press W, ALL nearby tentacles slam the target. In a zone with 3+ tentacles, a single W press triggers 3+ simultaneous slams, each healing you for 5% missing health if they hit a champion. This is why fighting Illaoi in her tentacle zone is a death sentence.
👻 E: Test of Spirit
Cost: 35 / 40 / 45 / 50 / 55 Mana | Cooldown: 16 / 15 / 14 / 13 / 12 seconds | Range: 950 | Speed: 1900
ACTIVE: Illaoi launches a tendril that stops at the first enemy hit, pulling their Spirit out in front of Illaoi over 0.75 seconds if they are a champion. The target is tethered to the Spirit for 7 seconds and revealed. The Spirit spawns with the target’s current health, armor, and magic resist.
A portion of damage dealt to the Spirit is transmitted to the tethered champion:
| Parameter | Value |
| Damage Transmission | 25/30/35/40/45% (+8% per 100 AD) |
| Tether Radius | 1500 / 1700 |
| Vessel Duration | 4 seconds |
When the Spirit is killed or the target leaves tether range, the target is marked as a Vessel for 4 seconds, slowed by 80% for 1.5 seconds, and tentacles autonomously attack the closest Vessel or Spirit. Vessels continuously spawn tentacles near themselves.
💡 Pro Tip: E is Illaoi’s defining ability. Landing E on the enemy laner is how you win every trade. Pull their spirit, W the spirit (commanding all tentacles to slam it), Q through it – the transmitted damage chunks the real champion from safety. If they run, they become a Vessel and get chased by auto-slamming tentacles. If they stay, you beat them down.
🌊 R: Leap of Faith (Ultimate)
Cost: 100 Mana | Cooldown: 120 / 95 / 70 seconds | Effect Radius: 500
ACTIVE: Illaoi gains displacement immunity and leaps into the air for the cast time, then slams her idol into the ground, dealing physical damage to nearby enemies. For each enemy champion hit, a Tentacle is summoned for 8 seconds (up to a maximum of 6 summons).
For the duration, Harsh Lesson’s cooldown is halved (2 seconds!), all Tentacles awakened by Illaoi are untargetable, will not show their hitboxes, and will not go dormant.
| Parameter | Value |
| Physical Damage | 150/250/350 (+50% bonus AD) |
| Tentacles Summoned | 1 per champion hit (max 6) |
| Duration | 8 seconds |
| W Cooldown During R | 2 seconds |
💡 Pro Tip: This is the ability that makes Illaoi Illaoi. Hit 2-3 champions with R and you spawn 2-3 UNTARGETABLE tentacles. With W on a 2-second cooldown, you’re commanding ALL tentacles to slam every 2 seconds, each healing you for 5% missing health per champion hit. In a 1v2 or 1v3 inside your R, you’re genuinely unkillable while dealing absurd damage. ALWAYS try to R when multiple enemies are close.
🎯 Strategies and Gameplay Tips
Early Game (Levels 1-6)
- Tentacle Zone Setup: Walk along walls to spawn tentacles before minions arrive. The more tentacles near your lane, the stronger your trades become. Set up tentacles on both sides of the lane – top and bottom walls.
- E Trading Pattern: Land E (Test of Spirit) to pull the enemy’s soul. Then W the soul to command all nearby tentacles to slam it. Follow with Q through the soul. The transmitted damage chunks the real champion. This is your bread-and-butter trade.
- Level 6 All-In: Leap of Faith at level 6 is one of the biggest powerspikes in the game. If the enemy jungler ganks you at 6 with tentacles set up, R both of them, W every 2 seconds, and watch the double kill happen. Illaoi is one of the best 1v2 champions in the entire game at level 6.
Mid Game (Levels 7-13)
- Split Push Pressure: Illaoi is a natural split pusher. Your tentacles provide permanent push pressure, and most champions can’t 1v1 you inside your tentacle zone. Push the lane, set up tentacles near the tower, and dare them to fight you.
- Vessel Harassment: After killing an E spirit, the enemy becomes a Vessel for 4 seconds. During this time, tentacles spawn near them and slam autonomously. This denies their CS, forces them to dodge, and keeps the pressure even when you’re farming.
- Tower Dives Invited: With R up and tentacles near an enemy tower, Illaoi can actually encourage tower dives from the enemy team. R gives displacement immunity on cast, and the healing from tentacle slams on multiple champions makes you incredibly tanky under your own tentacles.
Late Game (Level 14+)
- Teamfight Positioning: Fight in corridors and chokepoints where tentacles can spawn on nearby walls. Avoid open areas with no terrain – Illaoi without tentacles is just a slow melee champion with no gap close. Narrow spaces = tentacle paradise.
- R Timing: Don’t R preemptively. Wait until 2-3 enemies are in range, then R for maximum tentacle spawns. Every tentacle spawned from R is untargetable for 8 seconds, making your zone impossible to dismantle.
- Objective Control: Set up tentacles around Baron/Dragon before the fight. Your passive spawns them automatically near terrain. When the enemy team contests, E the carry’s spirit, R the frontline, and W on repeat. The healing from multi-champion tentacle hits makes you the ultimate zone controller.
❌ Common Mistakes and How to Avoid Them
- Fighting Without Tentacles: Illaoi without tentacles is pathetically weak. NEVER fight in open areas far from walls. Always set up your zone first – walk along walls to spawn tentacles before engaging. If there are no tentacles around, DON’T fight.
- Missing E and Still Fighting: Test of Spirit is your entire laning power. If you miss E, you lose the trade – back off and wait for cooldown. Don’t commit to a fight without landing E first. It’s a 16-12 second cooldown early, so respect the window.
- Using R on One Person: R spawns one tentacle per champion hit. Using it on a single target gives you one tentacle. Using it on 3 targets gives you 3 untargetable tentacles. The power difference is massive. Save R for multi-enemy situations whenever possible.
- Chasing Enemies Out of Zone: Illaoi’s biggest weakness is mobility. If the enemy walks away from your tentacle zone, LET THEM GO. Chasing means leaving your tentacles behind, which means you’re now a slow melee champion with no CC and no damage. Zone control means staying in the zone.
⚙️ Recommended Build and Itemization
Core Items
- Black Cleaver: The highest-priority first item. Each tentacle slam stacks armor shred on every target hit. In a multi-tentacle zone, you reach full Cleaver stacks in 2-3 seconds, shredding enemy armor for yourself and your team.
- Iceborn Gauntlet: Provides Sheen proc on W (auto-attack reset), armor, ability haste, and a slow field that keeps enemies trapped inside your tentacle zone longer. Perfect synergy with W’s 4-second cooldown.
- Sterak’s Gage: Massive AD scaling (tentacles scale with 110% AD), a shield when you get bursted, and tenacity. The shield proc during R fights keeps you alive through burst damage while your tentacle slams heal you back up.
Situational Items
- Spirit Visage: Increases ALL healing by 25% – including tentacle healing from passive. Every tentacle slam on a champion now heals for 6.25% missing health instead of 5%. In multi-tentacle R fights, the amplified healing is absurd.
- Sundered Sky: First hit against champions heals you. Combined with W auto-reset and tentacle healing, this adds another layer of sustain that makes Illaoi impossible to kill in extended fights.
- Thornmail: Against heavy healing comps. Tentacle slams apply Grievous Wounds to everyone hit, reducing enemy healing across the entire teamfight zone.
⚔️ Counter Picks & Matchups
✅ Illaoi Counters
1. Renekton
Why: Renekton’s dash-in, burst-trade pattern puts him directly inside your tentacle zone. He can’t disengage fast enough after his E to avoid tentacle punishment. Your tentacles outrade his short trades. At level 6, his R gives him more HP which just means more targets for your tentacle slams to heal off.
2. K’Sante
Why: K’Sante needs to fight in melee range, which is exactly where your tentacles obliterate. His tankiness doesn’t matter because your tentacle damage scales with AD and ignores his resists through Black Cleaver shred. If he ults you into a wall, you’re now near terrain where more tentacles spawn.
3. Jayce
Why: Jayce’s ranged poke can’t outpace your passive tentacle healing. When he switches to melee form, he’s trapped inside your tentacle zone. Your E spirit pull forces him to either fight inside your zone or walk away and become a Vessel.
❌ Illaoi is Countered By
1. Vayne
Why: Vayne’s mobility makes E practically impossible to land. Her Tumble (Q) dodges your predictable tentacle slams, Silver Bolts (W) shred your health regardless of armor, and Condemn (E) pins you to walls. She kites around your tentacle zone effortlessly and melts you from range.
2. Kayle
Why: Kayle plays safe early (which you can’t punish due to her range after 6), then completely outscales you. Her ultimate makes her invulnerable during your R window, negating your entire all-in. Post-16, she destroys you from range while you can’t reach her.
3. Gwen
Why: Gwen’s Hallowed Mist (W) makes her untargetable from outside the zone – meaning your tentacles can’t hit her. Her %max health true damage cuts through your sustain, and her mobility with E lets her dodge your E and reposition around your tentacle zone.
FAQ
Q: What’s the most important ability to land?
A: E (Test of Spirit) by far. Landing E wins trades, forces the enemy into your tentacle zone or makes them flee as a Vessel. Missing E means you lose the trade. Your entire laning phase revolves around E accuracy.
Q: When should I use R?
A: ALWAYS when 2+ enemies are in range. R spawns one tentacle per champion hit, and those tentacles are untargetable for 8 seconds. 1v2 with R is Illaoi’s bread and butter – you actually want to be ganked. The only time to R on one person is if it’s a must-kill situation.
Q: What skill order should I max?
A: Max E first for damage transmission scaling and cooldown reduction (16 → 12 seconds), then Q second for tentacle damage increase (10% → 30%), then W last. E max makes your spirit pull trades increasingly devastating. Take R at 6, 11, 16.
Q: Grasp or Conqueror?
A: Grasp of the Undying is the highest WR keystone (51.5% WR). It provides sustain in short trades, HP stacking, and Resolve tree access (Bone Plating, Overgrowth). Conqueror is viable for extended all-in fights but requires committing to longer trades.
Q: Is Illaoi good for beginners?
A: Illaoi is unique. Her kit is mechanically simple (land E, press W, press R), but understanding WHEN to fight and WHEN to walk away requires game knowledge. The tentacle zone concept is unlike any other champion. Easy to pick up, medium to master.
Q: Why is Illaoi weak in teamfights?A: She’s not weak in teamfights – she’s weak in the WRONG teamfights. Open-area fights with no terrain for tentacles are terrible. But fight in jungle corridors, near Baron pit, or around dragon wall, and she’s a monster. Her weakness is mobility and getting kited, not teamfight damage.
