The "Trickster Gods" mechanic is a brilliant risk-reward system. Players can be possessed by spirits that grant powers but force personality changes. The Tomb of Annihilation PDF details the roleplay flaws, such as "I never stick to a plan" or "I am terrified of blood." DMs need to enforce these. The digital text makes it easy to copy the specific flaw to the player. It leads to hilarious and tragic roleplay moments. The PDF helps track which player has which god, as the spirits can swap hosts. It adds a chaotic, psychological layer to the dungeon delving.
