I think I said it a while ago, that I was thinking in taking either Disguise self or Silent Image, though I must say I was considering leaving Thunderwave instead of Chromatic Orb at that point but that diamond... Any way I'm thinking being small might render disguise self a bit less useful while also considering Jill doesn't speak much languages so I would definitely be going for Silent Image, guess that would also be much more interesting considering the wild surge randomness :P
