Good (7/10)

Illaoi is a powerful, aggressive champion capable of consistent One-Turn Kills (OTKs). If she gets to pull off her game plan, she can deal massive damage, overkilling the enemy nexus. She is very all-in though and can struggle to recover from disruption.

Tentacle Mastery
  • Harsh Lesson icon

    Illaoi naturally has Overwhelm so the free strike to eliminate the enemy blocker generally translates to additional nexus damage.

  • Crownguard Inheritance icon

    When I level up, Rally.

  • Spirit of the Buhru icon

    Power: Allies that cost 1 or less have Overwhelm, Quick Attack, and Fury.

Strategy

This focuses on eliminating the enemy nexus with a single attack chain of attacks. Attack once, level up, attack again. She gains so many stats from her Tentacle that their combined power usually overkills the enemy nexus.

Turn 3 OTK

Strategy

Drop Illaoi and win. This build lets you attack up to three times on turn 3, usually eliminating the enemy Nexus. If the enemy was able to interrupt this plan, then you're in a rough spot.

Gameplay Tips
  • Protect the Tentacle

Illaoi's entire game plan revolves around her Tentacle. If it gets stunned, frostbitten, or obliterated, her win condition is severely compromised. Prioritize its survival above all else.

  • Bait Out Removal

Consider passing the turn to let the AI spend its mana before deploying Illaoi or key Spawn spells. This minimizes the risk of cheap removal or Obliterate effects destroying your Tentacle before you can attack.

  • Beware of Lulu

The Lulu encounter is a hard counter to Illaoi. Lulu's adventure power can transform your massive Tentacle into a 1/1, completely neutralizing your primary threat. Approach this matchup with extreme caution.

  • Drafting Strategy

Prioritize powers and cards that generate units (Spawn) or provide mana acceleration. Spells like Answered Prayers and Tentacle Smash are critical for scaling your board state quickly.

  • Leverage Innate Overwhelm

Illaoi naturally possesses Overwhelm. Focus on buffing her stats and ensuring she can attack safely to push massive damage directly to the enemy Nexus, especially when combined with Rally effects.
