Anybody had any cool custom weapons? Like, something your DM made up and included in part of a quest or something you had made by a smith? I've had gauntlets that counted as claw attacks, a medium great sword that did large size damage, a three headed flail and a fire sword that had a BFG 9000 style "breath attack" that hit anything within my field of view (width wise anyway, the distance covered about 30 feet). What's the coolest made up weapon anybody else has encountered?
