Mechanics (Hardmode)

Power meter
⬥ Displays the connection between Zemouregal and Vorkath, affecting damage absorption and damage dealt by Vorkath.     • Each next phase increases it by net 25%.     • Empowered zombies can increase it by 50%.     • Power meter disappears when vorkath leaves at zero lifepoints. ​
Dragonfire Breath
⬥ Vorkath charges up and deals a big magic hit.     • Damage is reduced by superantifire or elderovlsalve
Zonal Ice Breath
⬥ Vorkath takes to the air and spews ice on his location that spreads outward, after which he comes back down.     • Can deal three magic hits and one MD melee slam.         • Can be avoided by moving away from Vorkath, also protecting summoning familiars.     • The magic hits damage Zemouregal and all minions caught within it. ​
Poison pools
⬥ Vorkath will stand on his hind legs and spew into the air, causing pools that hit hard typeless damage to appear.     • Phase 2: Green poison pools, hitting up to 3k.     • Phase 3: Purple poison pools, hitting up to 5k.         • Every hit taken increases Zemouregal's Empowerment debuff by 5%, increasing damage taken.     • Can be accompanied by the voiceline: Spew your venom, my malformed pet!
⬥ Vorkath flies up high to freeze the whole arena by air strike. If not stopped, all in the arena will be hit ~15k magic damage, killing summoning familiars.     • Using the balista (extra action button) while Vorkath is up will shoot Vorkath down, preventing the attack and dealing a 10k hit to Vorkath.         • Can fail if done right before Vorkath returns!     • cade devo reflect can be used alternatively.     • Can be accompanied by the voiceline: Cast my glorious vengeance down upon them! or Cut them down without mercy!
Power Meter and Damage Reduction
⬥ The power meter increases Vorkath's damage dealt by auto attacks as well as mechanics. ⬥ While Vorkath is around, Zemouregal takes no or reduced damage.     • Every phase transition Zemouregal gets hit 10k by Vorkath, reducing his damage reduction by 10% (100%→90%→80%). ⬥ If Zemouregal gets hit while shielded, a green orb is sent to Vorkath, giving him damage absorption based on the damage dealt on Zemouregal.     • Vorkath's damage absorption is multiplied by the power meter % and vuln. ​
⬥ Zemouregal summons two minions, one of each type.     • This is a time-based mechanic which resets on phasing.     • Combat minions (36k constitution per player)         • Skeleton ranger         • Zombie warrior         • Skeleton knight         • Phantom Spellcaster     • Support minions (6k constitution per player)         • Ghost Healer, heals Vorkath 1000 lifepoints.         • Zombie Shielder, gives Vorkath a shield, reducing incoming damage.         • Empowering Zombie, adds +50% to the power meter temporarily. ​
Bone Spikes
⬥ Zemouregal makes a dust cloud appear on every player's location, where 4.2s later spikes shoot out of the ground.     • This is a time-based mechanic which resets on phasing.     • Can deal up to 8k soft typeless damage to every player in the 7x7 area.     • Can be avoided by moving away from your location. ​
