Strategy
Corla is surrounded by 2 Twilight Zealots (heroic: 3). When the fight starts, the zealots will be inactive, but will begin gaining stacks of Evolution. If a zealot reaches 100 stacks, it will transform into an Evolved Twilight Zealot, which attacks normally and deals high damage.

The key to the fight is preventing these transformations. Each zealot has a purple beam connecting it to the nether drake at the top of the room. If a player stands in that beam, he will 'steal' its effect; the zealot will stop gaining Evolution, and the player will get it instead. If a player reaches 100 stacks, he will transform and become mind-controlled, likely wiping the group.

Evolution has a 15 second duration, and takes 20 seconds to reach 100 stacks. This means that a single player can trade the beam back and forth with an assigned zealot every 15 to 20 seconds without either of them evolving. On heroic mode it is necessary to do this to all 3 zealots for the entire fight, as a zealot evolving tends to be disastrous. On normal mode, however, some groups find it easier to alternate 2-3 players in one beam while letting the other zealot evolve, killing it, and returning to the boss. On heroic mode, since three players are necessary, and there aren't enough players to keep all of the beams under control, a good rule of thumb is to sit in the beam until you have around 70-80 stacks, jump out of the beam and wait for the debuff to wear off before jumping back in the beam. Rinse and repeat as needed.

The last problem is that Corla periodically fears a random player using Dark Command. Dark Command is a 2-second cast and must be interrupted, since a player stepping out of his beam at the wrong time will likely result in an evolution. If a player does get feared away, one of the players who weren't on a beam before must take his place until his stacks clear.
