Evolution – Corla drains the essence of a Nether Dragon corpse and channels this essence into Twilight Zealots. The Evolution effect then rapidly stacks on the Zealot, and if the number of stacks reaches 100 then the Zealot will transform into an Evolved Twilight Zealot for the remainder of the encounter. The stacking Evolution effect lasts 15 sec.If a player moves into the beam between a Twilight Zealot and the Nether Dragon corpse, that player starts to gain the Evolution effect and begins to evolve. If the Evolution effect stacks to 100 on a player, then the player will transform into a Twilight Drakonid.
