Hela's House of Dark Delights for Tunnels & Trolls

A strolling minstrel with a silver-stringed guitar approaches your table, takes one look at you and composes a limerick of ridicule. "Who was that?" you ask. "That was John Taliesin, the greatest singer in the world," the Elf tells you, "and his limerick will be repeated for 100 years. Now it is time for you to go" (You don't know it yet, but your Charisma has just been reduced to 3. This is a permanent and unalterable change [i.e. your Charisma rating can't be changed by magic, not even by dungeon level magic] except for level bonuses to raise your Charisma again.)
