This is really cool, but would it be plausible for a charector with perform(war bell) using the bludgeoning form of damage to maybe cause the shaken condition on the first hit on a opponent(with a succesful perform check of course), maybe for one or two rounds, i have no idea what the fortitude save would be. Maybe with just the Heavy Warbell. Anyways these are cool, a monk should be able to pick them up as special monk weapons(maybe swapping out another weapon). Still, it would be so funny to see a group of PCs getting beaten by a NPC using a bell =D, maybe two.
