Description
The Shadow-Morph is the embodiment of chaos, but not evil. It is able to change its form whenever it wants, but never can it change its whole body; for example, it might use shape change to turn his arm into a weapon of some sort. It cannot turn part of itself into something heavier than it can carry or you have to succeed a strength saving throw at disadvantage. The Shadow-Morph also looks nearly invisible while nighttime, and anybody doing a perception check rolls at disadvantage.
