Wizards of the Coast created a masterpiece of trap design with this module. Unlike other adventures where traps are simple damage dealers, here they are complex puzzles. From the magnetic statues to the mirrored halls, every trap tells a story. When you read the Tomb of Annihilation PDF, you realize that the dungeon is an adversary character in itself. DMs need to understand the trigger mechanisms and the solutions clearly to be fair to the players. The digital version allows for zooming in on diagrams and reading the "DM only" text clearly, ensuring that the lethal nature of the tomb is executed exactly as written.
