Publisher's blurb:
This is the 75th in an ongoing series aimed to provide the overworked DM with ready-to run encounters. The PCs face the pre-historic horror of the necrosaurus.
Created during an ancient civil war, the necrosaurs, were made from the bones of tyrannosaurus rexes and other predatorial dinosaurs. These creatures were not mere animated bones but were infused with necrotic fire and proved very effective as weapons.
While this civil war ended differently in different realities but in most of them at least a few necrosaurs survived, often buried, or sealed away in ancient dungeons.
A single necrosaurus is CR 8. The encounter can easily be modified by increasing the number of foes.
It includes a history/background for the encounter, a map, and monster stats. The companion ZIP file contains JPEG versions of the maps (with and without grid), the Word file of the encounter, and a Fantasy Grounds Unity Module file.
