Something that I've always wondered: what is the damage necessary to poof a gem? I mean, Pearl got stabbed by a sort of training sim that she created and poofed, but got smacked around by a crazy Sugilite and got up. And Sadie poofed an invisible Gem monster with a pointy stick/crude wooden fishing spear. And who knows how guns affect Gems (supposing Candice uses guns to fight monsters)?
