Supernatural Gift: Hollow One

As a Hollowed one, the void left behind your departed soul is filled with strange necromantic magic. Becoming a hollowed one is a supernatural gift, and not a feat able to be granted by a normal ASI giving level. Talk to your DM about using this feat to start out with, or choosing to bring back a character as a Hollow one after death. This gift bestows upon you the following traits:

Ageless. You don't age, and effects that would cause you to age don't work on you.

Cling to Life. When you make a death saving throw and roll a 16 or higher, you regain 1 hit point.

Revenance. You retain your creature type, yet you register as undead to spells and other effects that detect the presence of the undead creature type.

Unsettling Presence. As an action, you can unsettle a creature you can see within 15 feet of you. The target has disadvantage on the next saving throw it makes within the next minute. constructs, undead, and creatures that can't be frightened are immune to this feature. Once you use this feature, you can't use it again until you finish a long rest.

The Hollow One was created by Matthew Mercer of Critical Role and is owned by him and the creators of Explorer's Guide to Wildemount. I'm only making this to have the features for a PC within D&D Beyond
