Assault on the Umbral Fortress | New 5th-Level Adventure for Fifth Edition

The Demiplane of Shadow is home to countless spiteful creatures whose cruelty is limited only by their imagination. While it's unusual for shadowkind to band together, occasionally a singular goal will arise that will draw multiple forces together. When this happens, the races of shadow might build a fortress of shadow. United under one dark roof, the creatures of shadow can plan, prepare, and execute their depraved designs.

Where to Add This Encounter

This side trek is designed for three to seven 5th- to 10th-level characters and is optimized for five characters with an average party level (APL) of 5. The Shadowfell Fortress design works best when it is placed at the front of a larger dungeon. Because it requires the characters to charge headfirst into multiple waves of creatures, the characters will need to have access to rest following the siege or, at the very least, plenty of healing supplies.
