i'm doing 5 priests and i've seen one other mentioned in the forums. I've also coincidentally heard about another on my server but have never crossed paths with them. I get strange messages from people who think im them though lol.

5 holy novas, nope. Costs too much mana. It's double the mana cost of mage AE and 1/3rd the damage. Better off aoeing with SWain and saving the nova for healing and lesser mobs.
