From publisher blurb:
The Tome of Encounters has over 40 detailed encounters, ranging in difficulty from Easy to Deadly, in 11 different terrain types. From shipwrecked pirates to chimera ambushes, lost treasures and secret portals, vampire lairs, and basilisk dens, there is always a quick encounter to add a bit of danger at a moments notice! Each encounter is tailored to its environment, average party level, difficulty, and includes level accurate rewards and treasure. Scenes are set up to be quickly inserted into any 5e adventure with little to no preparation. Monster statistics are provided in this bookmarked PDF for easy reference. Some encounters even have additional "hooks" that the GM can use to engage their Players in additional side-quests! Each one to two-page encounter is also presented with a full-color map that details the environment the encounter takes place in and gives a grid that can be used to demonstrate monster and Player positions. The maps will also be included without words or other decorations so the GM can re-use them as they see fit.
