***Prerequisite:** Be Undead; have been cursed by a Shadow or died whilst so cursed. (You may take this feat reactively, replacing the last feat that you took.)* Something went terribly wrong… the last thing you remember was fighting strange shadowy forms that seemed to meld with the dark and feeling a dreadful coldness seeping through you to your very bones. That hasn’t gone away, but you’re awake now. You gain the Undead creature type if you do not already have it. **Sunlight Sensitivity.** You suffer disadvantage on attack rolls and perception checks when you, or whatever you are affecting or interacting with, are in direct sunlight. **Darkvision.** You gain 60 feet of Darkvision, if you already had Darkvision, this extends the range by a further 60 feet. **Unsleeping.** You now require only half as much sleep as you did before to gain the benefits of a long rest. If you previously tranced then you no longer require sleep, only requiring a 4-hour period of light or little activity. **Uneating.** You still eat but now you require one less Supply every other rest, e.g. if you require one Supply per long rest you now require one Supply every two short rests to gain the benefits of a long rest. **Unbreathing.** You may hold your breath for double the time you would normally expect to be able to and the number of rounds taken for you to suffocate doubles. **Shadow Sneak.** When you are obscured by dim light or darkness, you may take the Hide action as a bonus action.
