This staff I've had fun with in 1 of my campaigns. Simply stated, no one knows all of the powers of the Staff of Dargath except for the few faerie tales told to children. I tossed this staff into the campaign & the mage thought he'd deciphered 1 of the tales & when they encountered a dragon he thought he was casting burning hands when a big fireball exploded right from the staff. That wasn't the worste of it. Dargoth appeared & demanded his arch-nemesis' staff be handed over. Dargath showed up shortly thereafter. Dargoth & Dargath with their centuries long warfare against each other erupted into spellcasting & trying to destroy the other. The party got rid of the staff as soon as possible & left the dragon to whatever became of it. I think the dragon ran off & hid to.
