This spell works on characters below lvl 45, so it's fun for PL'ing. Which is cool cause PL'ing as a shaman at lower levels was kinda annoying. Druids and Clerics can do DS type stuff, nice to have something for Shamans to PL with.
Only annoying part is that it's group only and short duration so you have to join group cast, and leave group but meh, it's something.
