Add a way to undo polymorph

[Dr Zoidcrab]

Not nearly as bad as old shocking touch. That just killed you no matter what. It's arguably as bad as old cluwning, but most people would rather be a cool animal than cluwne the whole round.

My main problem with it lies in it's capacity for cheese. Polymorph should largely be a griff spell, not a 'kill something quickly' spell.

When combining it with something like fireball or the cthulhu staff its the eqivalent of Rathen's secret + shocking grasp. Had a wizard round where the wizard just went around polymorphing people out of phase shift and then immediately casting fireball, killing them instantly.
