Guide: Mighty Ukko

In short

Mighty Ukko is a legendary support champion from the Skinwalkers faction. He excels in Hydra and the Arena thanks to AoE buff striping, block buffs, a revive with Block Damage, and buff stealing. Build him for survival and speed.

Strengths

  • AoE A1 with a 75% chance to place Decrease ATK for 2 turns — great for wave control.
  • P Owerful A2: attacks twice, each hit has a 100% chance to remove 2 buffs, then applies Block Buffs and -50% ACC for 2 turns on enemies without buffs.
  • Full team revive with 40% HP and Block Damage, plus a 30% SPD buff for all allies. Even without dead allies, the SPD buff is applied.
  • P assive: 50% chance to steal 1 random buff from an enemy whenever they gain a buff. Stolen buffs become protected — excellent control.
  • Aura: +20% SPD in all battles, one of the best auras in the game.

Weaknesses

  • Low base DEF (1,112), needs significant HP and DEF from gear.
  • Long cooldowns without tomes; fully booking the revive reduces it to 4 turns, but requires investment.
  • Vulnerable to crowd control and buff removal before taking a turn.
  • Not as outstanding in Dungeons (4.0) or Doom Tower (3.0) compared to Hydra/Arena.

Where to use

Best: Hydra (5.0) — passive steals buffs, block buffs shuts down dangerous heads; Arena (5.0) — mass strip, block buffs, and revive make him a top pick; Chimera (4.5); Faction Wars (4.5). Good: Bommal (block buffs helps), Iron Twins - Power. Average: Dungeons (4.0), Doom Tower (3.0), Clan Boss (3.5).

Stats and gear

P riority: SPD (250+), ACC (350+ for Hydra/Arena), then HP% and DEF%. Ignore Crit. Recommended sets: Regeneration for sustain; P ercetion for ACC; Stun for additional control; Stoneskin for Arena; Bolster for shield support. For Arena, Stoneskin with high SPD and ACC is common.

Masteries and blessings

F or PVE (Hydra, Dungeons): Offense and Support trees, taking Gathering Momentum, Invigorated, Targetfinder, Buff Depletion. F or PVP (Arena): Defense and Support with Damage Mitigation, Bolstered Defense, plus key Support masteries. Blessings: Brimstone for Hydra/CB; Temporal chains for Arena.

Tomes

P rioritise A3 (revive) and A2 (buff strip). Book A2 to reach 100% removal chance, and A3 for the cooldown reduction to 4 turns. A1 can be booked later for a higher Decrease ATK chance.

Verdict

Mighty Ukko is a must-build champion for anyone aiming to conquer Hydra and dominate Arena. His combination of control, revive, and speed aura is nearly unparalleled.
