If you’d like a Photoshop layered revealable map for exploring Tomb of Annihilation’s Chult, download this PSD and reveal away! It is designed in a similar fashion to the player map that was provided with the Tomb of Annihilation hardcover. It contains layers for both the DM and the player in case you want to swap between them. You could even erase portions of the player map to reveal the DM portion underneath if you want to put new locations on the map. There are some locations that will shift locations between the players and DM version. That’s just how they were provided by WotC; no modifications have been made.
