Flesh to stone the pudding and shape it into a hammer..........done.
"Flesh" to Stone, not Yogurt to Stone.
Anyways, my own 2 cents.
Flesh to Stone always seemed to be one of the powerhouse spells preferred to the community simply because theres very little ways to be immune to the spell or counter the spell via buffs. It really hurts rogues and wizards who don't have any fortitude saves, but I don't think its very hard to get a few certain low-cost items to boost some saves to help.
Its definitely a spell that needs to be cast with care and consideration to victims, as its almost, if not a bit worse, as killing someone; Raises don't cost as much (in comparison to StF scrolls), and clerics can cast Raise Dead a bit more freely in certain situations then wizards casting Stone to Flesh to fix it. If its duration ends up being permanent on the victim, its really an RP killer in my opinion. I personally wouldn't want to sit around for hours on end emoting [is a statue] until being fixed, but I suppose it would depend on where it happened, I like spectating sometimes.
Likely one of my characters worst fears, which is why she's taken a concerted effort to protect herself from it.
