I had plans for that mana, Kel'thuzad!
Sciveral was (alas) not present for our first kill of Kel'thuzad, but he still exclaimed our signature line for this fight.
After a fun three-and-a-half minute prelude fighting all manner of banshees, skeletons, and abominations, Kel'thezud strikes! Healers need fast twitch spellcasts for ice block victims. Melee need to maintain distance. Everyone needs to be ready to move precisely to avoid red circles of death.
