My own notes for explaining the General Vezax fight in Ulduar.
This is a single phase fight. Most mana regen doesn't function in this fight, so healers and casters need to be careful. Ranged should spread out but should all stay in roughly the same area.
Vezax will sometimes debuff someone with Mark of the Faceless - this person will transfer health from nearby players to Vezax, so run away! This means you can never bunch up too much.
Vezax will cast Searing Flames every 5-10 seconds (2 sec cast time, large spinning effects around him). This must be interrupted, or the tank will die.
Vezax will cast Surge of Darkness every minute - he will need to be kited until it wears off.
Every 10 seconds Vezax will cast Shadow Crash at a ranged player - move before it hits you. It will leave behind a dark pool that ranged DPS (not healers) should stand in.
Every 30 seconds Vezax will spawn a Saronite Crystal. Kill them. When they pop they will leave behind a green pool. Standing in this will regen your mana but will also deal damage. Stand in it until you get 5 or 6 stacks then get out!
