Buff or Remove Exploding Ammo
According to learnDB it's 2d5 flat damage in addition to the original hit. Unsure if that's exactly right, but it's completely negligible damage versus nearly all targets after the AC reduction, comparable to a magic dart. That's for some reason as loud as a fireball. Might as well be "noisy ammo that always mulches" in it's current state; either just remove the brand (when an enemy throws it the message spam about it failing to hurt all the nearby plants is annoying anyways), or make it actually use throwing skill/base damage for the explosion instead of the very weak flat damage.
