Guide

An iron colossus with two poles. It pushes heroes apart and pulls them together, turn by turn.

Deadly Scatter: A 5 second cast. When it ends every hero takes damage by the distance to their nearest ally: 90% of their health at 3 m, falling to 12% at 11 m or more. Anyone within 3 m of another hero is struck down.
Deadly Gather: A 5 second cast that places a blue ring (5.5 m) somewhere in the arena. When it ends a blow worth 275% of a hero's health is split between everyone inside the ring. Anyone outside it is struck down.
Polar Flux Below 50%: Scatter and Gather come back to back: three casts in a row (5, 4.5 and 4.5 seconds), each a second after the last one lands.
Iron Sweep: A 120 degree cone in front of Vorthax fills and bursts for heavy damage.
Filing Storm: Three circles fall around the heroes.
Lodestone Grip: Its melee swing adds a Brand stack for 12 seconds (12% more damage from Vorthax per stack, up to 8).
Enrage: After 5 minutes Vorthax hits twice as hard and much faster.
