The Mass

In D&D 5e, damage resistances and immunities play a critical role in the tactics of a combat. But they could be better.

The Mass is a monster designed to push parties to their limits by befuddling the usually safe physical damage types. Its body's strange substance shifts in hardness based on the forces applied to it. What would be a concussive strike instead renders its body tougher than adamantine, while a slice turns its skin into a gelatin, entangling the offending weapon. It seems to be adapted to the pseudopods and claws of the worlds beyond our own, but is ill prepared for anything that can stab forcefully enough. Magical weapons aren't going to be the panacea that they usually are, and without the right damage type, these creatures will prove deadly. Create better, more exciting tactics for your D&D 5e games using this threatening aberration.

Designed using the Day 20 Dynamic Challenge System, this monster scales to suit any level. Whether your party is just starting or are at the end of a high level campaign, this stat block will serve you well!
