wands, staves and/or scrolls? Heck save for shifters most mages have access to spells that can do more damage or whatever. Also don't Poisoner thieves get the ability to do something similar to this through the launch grenade skill? I mean, it sounds alright and all but really. Gameplay-wise it looks like it might be a bit redundant. That's just me.

Edit: Typoed shifters.
