It is a little wierd with regards to the Mastery of Shaping type of effect embedded in the spell. If not for that I would say it would be a 4 or 5th level spell. The spell makes sense in a way and I don't think it is overpowered as long as you keep the "The caster can choose which creatures in the area are affected and which are not, although he must be able to see the creatures." requirement
