Assuming you survived last week without turning into a puddle of priestly sludge or quitting your guild (cough, cough), it's now time to move on to the sixth and seventh encounters in Dragon Soul, Warmaster Blackhorn and Spine of Deathwing. Just like last week, I want to remind you that you'll need to be familiar with the basic mechanics of these encounters to follow along with my priest healing guide. For Warmaster Blackhorn, try checking out LearnToRaid.com for a video guide and Icy Veins for a written guide.
Warmaster Blackhorn is a pretty straightforward fight as far as healing is concerned. The key is to keep your eyes open to what is going on instead of staring intently at your raid frame the whole time. Much of the healing required will be in response to effects you'll see on the ground first, so if you're good at clicking players instead of health bars, you'll be way ahead of the game.
