Possession

As an action, your body becomes immaterial, and your spirit dives into a Large or smaller creature you can see within 10 feet of you in an attempt to possess it. This target must make a Charisma saving throw. A creature with a challenge rating greater than your witch level automatically succeeds on this save. On a failed save, you disappear and the target becomes incapacitated and possessed; you gain control of its body but don’t deprive the target of its awareness. While possessing the creature, you can’t be targeted by any attack, spell, or other effect. You maintain your Intelligence, Wisdom, and Charisma and your alignment, but otherwise use the creature’s statistics. You don’t gain access to the target’s knowledge, class features, or proficiencies.

For the purposes of spells and effects which can end possession, such as the spellDispel Evil and Good, you are treated as an Undead spirit and can be banished from the target, returning to your own body, which rematerializes within 5 feet of the target.

This possession lasts for 1 hour, or until the body drops to 0 hit points or you are forced out by a spell or other magical effect that ends possession.

Once you use this grand hex, you can’t do so again until you finish a long rest.
