It Consumes

From publisher blurb:

A giant slime has begun rolling through Vladenosk, picking up everything in its wake and only growing in size as it consumes. It is the product of Mouser the Mad Alchemist, a halfling who had been experimenting with elevating his body to something beyond its mortal limits. Whether this final crescendo is a grand success or a massive failure is irrelevant; people are dying, and the slime must be stopped.

It Consumes is a Q-Encounter, or Quick-Encounter, that can be run for a group of four to six players with 12th-level characters. This encounter would be considered a ‘medium’ to ‘hard’ encounter.
