Just ran a game where a single player, playing a Paladin class from your Hallowed supplement, was able to defeat Ogyr King Pom, with the aid of one of Trumzee's sons (who was equipped with the Harvester of Sorrows he took from Flab). I had it that Randolf, The Copper Prince of Schleswig (from Monsters!) stole Princess Lavina (who I said was his half-sister) and sold her to Pom in exchange for a political alliance, as part of a plot to dethrone Fathmu IX. It was an impressive fight!
But here is a question: how does one destroy the indestructible femur of St. Martinius the Pure?
