D&D 40th Anniversary Blog Hop Challenge Day 4

First dragon your character slew (or some other powerful monster)?  A wyvern was our victim.  It was a lucky critical and prior to that had cut our dwarf in half.  I was a Paladin named Kincaid and we were playing a mash up of DnD Rules Cyclopedia and ADnD 2E, it was weird game run by one of my oldest friends, Barry.  While hiding from a troll, it urinated on our Mystic.  Like all of Barry's game, we ended up dealing with traps from Grimtooth's dungeon and had characters so maimed we abandoned the game.
