Could be.  I thought it might be a little overpowered at first, actually, but I didn't really look at how much damage low-level casters did compared to melee characters, especially characters with large weapons (i.e. Tess does 1d10+4 damage per hit, but Lyra's lucky if she can equal Tess's minimum damage).  I think casters will be fine once they get to higher level spells, but they could use a bump at low levels.<br/><br/>I do like the idea of not letting Lyra know the spell at first though, since really, when would you need to know a spell that can sever tentacles? :P
