Spell details for Disseverment  

I wouldn't cry nerf on this spell just because it did some decent damage. The damage you posted is about on par with the Ninja weaponskill Blade: Ku. They're both dependent on TP for accuracy and have 5 hits. Now, compare that to other multi-hit WS in the game, such as Rampage, Asuran Fists and even hexastrike. All three of those have the same or more number of hits and do more damage. Now, I realize this isn't a WS, so you don't have to have TP to use it, but it still has a 74 MP cost. That means at 75 you can do roughly 10 of these, provided the BLU has subbed a mage job, otherwise the BLU will only have enough MP for 8 of these before they're out of MP. So while this spell has the potential to do good damage, it's not like a BLU can spam it, thus breaking the game.
