He will not cast this on players within 15 yards of him. Searing Flames - Searing Flames takes 2 seconds to cast WoW Gold, and must be interrupted. If you do not interrupt this ability, it is virtually a raid wipe about WoW Gold.

Has a casting time of 3 seconds, so you should expect to see it slightly less than once a minute. This ability empowers Vezax with dark might, increasing physical damage by 100% but reducing movement speed by 55%, for 10 seconds to get WoW Goldld.

Mark of the Faceless - Inflicts an ancient malediction on a target, siphoning 5,000 healths every second from enemies near the target, for 10 seconds. He will not cast this on players within 15 yards of him about WoW Gold. However, if there are no such targets outside the 15 yards, hell cast it on your melee folks anyway.

Keep an eye out for the floating green ball, called Saronite Vapors. It floats around the room once it is spawned, but Death Knights can Death Grip it to the raid. Up to eight of these crystals will spawn. When destroyed, a green puddle is formed on the ground. Players who stand in this puddle will take Shadow Damage, but also regenerate mana to get WoW Gold. (This is significant since Aura of Despair is keeping you from taking advantage of most mana replenishment.) Putting it all together

Aura of Despair is the defining ability for the fight against Vezax. It prevents most of your mana-regeneration abilities from having much effect. As a result, your team needs to be on point about the Saronite Vapors.
