Adventure Guide

In a desperate attempt to save the family brewery, Uncle Gao set about concocting what he believed would be the ultimate ale, a full-bodied elixir of depthless flavor. Yet his bold experiment resulted in a bitter and extremely volatile alemental creature, dubbed Yan-Zhu the Uncasked.

This Bloat causes brew to gush from their ears for 30 sec, inflicting 20000 (Heroic: 50000) Frost damage to and knocking back targets in a 10-degree cone on either side of the bloated player.
    • Spell nature sleep.png  Blackout Brew Important — The heavy Blackout Brew inflicts 15000 (Heroic: 30000) Frost damage to all players and applies 3 stacks of Blackout Brew. Stacks can be removed by moving and jumping. If Blackout Brew reaches 10 stacks, the Brew stuns the player for 10 sec.

    • Yeasty Brew Alemental — Yan-Zhu summons forth Yeasty Brew Alementals to aid him.
      • Inv misc lifeblood.png  Ferment Important — The Yeasty Brew Alemental fires a fermentation beam towards Yan-Zhu the Uncasked, but players may intercept the beam and receive its effect by standing between the two Alementals. The fermentation restores 1% of health and mana ever 1 sec. to the affected target.

    • Inv drink 05.png  Carbonation Important — Yan-Zhu fills the room with Carbonation for 20 sec. The Carbonation inflicts 1000 (Heroic: 10000) Frost damage every 1 sec. to enemies that are close to the ground and prevents them from attacking of casting spells due to acute asphyxiation. In addition, Carbonation causes Fizzy Bubbles to spawn.
      • Fizzy Bubble — Clicking on a Fizzy Bubble grants the ability to fly for 20 sec.
    • Spell misc drink.png  Wall of Suds Important — Yan-Zhu periodically summons forth walls of sudsy brew. Inflicts 50000 (Heroic: 100000) Frost damage every 0.50 seconds to players that stand within the wall and stuns them for 5 sec.
      • Ability heroicleap.png  Sudsy — The sudsy nature of Yan-Zhu grants players the ability to jump extra high.


Bloat must be dealt with cautiously when watching your boundaries regard of role. The Blackout Brew must be removed by moving around or back and forth. Take out the bubbles that surround the boss because it'll decrease damage dealt. The Yeasty Brew Alemental can either be killed asap or stand in line of healing. Don't let it go on the boss, it'll be a long boring fight. You get an ability called Sudsy they'll make you jump higher. Use it when he casts Wall of Suds, otherwise it'll do massive damage and stuns you. During the Carbonation phase, grab a Fizzy Bubble to fly up, otherwise, you're silenced.
