Shadow Walker (5e Feat)
From D&D Wiki
Prerequisites: must be a type of undead, Dexterity of 13 or more.
You're able to change your undead soul into shadows and meld into other shadows. You gain the following benefits:
- When in shadows that are large enough to cover your body when at least sitting, you can use your Hide action to become invisible.
- Once a day, you can cast the spell misty step, so long as there is another shadow that can cover your body within the spell's range.
