Dangerous Scenarios: Mutant Metal eater (Patreon)

The more experienced a group of adventurers gets the less concerned they are with the threat posed by monsters they've already bested once. The mutant metal eater is no such monster—the creature the PCs are expecting to find is far deadlier! Includes a mutant rust monster (CR 8) and supermutant rust monster (CR 12). This Dangerous Scenario for parties of 5th–6th level or 8th–9th level was deviously designed by Chris Davies, illustrated by Indi Martin, with interior art by Guilherme Sommermeyer and cartography by Dyson Logos.
