A Dungeon Master must manage these personalities on top of the monsters. Having the Tomb of Annihilation PDF open helps in quickly checking the benefits and drawbacks of each god, from Kubazan to Moa. This layer of gameplay adds chaos and fun to the final chapters. The digital version of the book helps keep these mechanics organized, so the DM can focus on the roleplay aspect of the spirits arguing inside the players’ heads.
