As a DM, did you ever use “madness rules” and monsters that can make you mad ? (For example, a game session “I have to go to a temple because my character has gone mad since I’ve deen this weird monster”) Thanks ! Yes, but not madness tables, though I've designed some for previous edition official D&D. I have specific sorts of insanity caused by specific things (poison, magic, psionic attacks, etc.). Insanity and poisons tend to get edited out of the game, and later replaced.#Realmslore
