Around 95%, 66%, and 33% remaining life, Feng siphons the essence out of a pre-selected statue of Mogu Champions' past, gaining their boon.
In Normal, this order will always be Fist -> Spear -> Staff.
Each Spirit absorbed gives a different set of abilities.
Tanks can use Nullification Barrier or Shroud of Reversal to negate or replicate boss abilities.
In Heroic, the order of statues is no longer pre-selected. Feng instead siphons from the statue nearest to him at around 100%, 75%, 50% and 25%.
Spirit of the Shield is a new Heroic only phase.
Lightning Fists shoots three shockwaves instead of one.
Every Spirit absorbed by Feng gives him a 10% damage buff.
The boss has a few mechanics present throughout all phases.
Feng imbues himself with the Spirit of the Fist, gaining three abilities: Lightning Lash, Epicenter, and Lightning Fists.
