For those who have never looked through Tomb of Annihilation then i really think you should as it is a great adventure that is lacking in many areas.

This helps out so much with a bunch of maps, a bunch of encounters some expanded encounters and some great new monsters for you to terrify your players with and make Chult even more of a scary place.

Most of all this has a bunch of maps that will help expand the land of Chult (that is the main issue with ToA).

The Encounters are great the expanded ones help you add something extra to your run of the mill random encounters which there is a lot of in Chult to take your game to the next level.
