Ok, yesterday's pledge was BC II, so me and 3 guildmates went for a vet run. I haven't been in this dungeon before so I didn't know the mechanics.
There was no problem at all, we've burned everything to the ground and then we've reached the final boss, high Kinglord Rilis. We've tried that on HM, wiped 3 times and on the forth we've managed to kill him.
I know that when he bubbles a player depending if it's a blue or a red bubble, when you land again you should run straight to the appropriate circle, blue or red, to dispel the dot that's on you.
I also know that when the 2 healing bubbles spawn, it's my highest priority as dps to destroy them because if they reach the boss they significant heal him.
Is there any other mechanics I should know that I couldn't figure out during the fight?
Final note: I've received 1 crystal from Rilis and 2 more when I've completed the pledge.
