Inspired by the investiture spells of Princes of the Apocalypse, the D&D 5th edition campaign by Wizards of the Coast, here is a homebrew investiture spell for the School of Necromancy.
- Investiture of Death (Cleric 6, Sorcerer 6, Warlock 6, Wizard 6)
Investiture of Death
Casting time: 1 action
Components: V, S
Duration: Concentration, up to 10 minutes
Until the spell ends, dark energy whirls around you, and you gain the following benefits:
- You are immune to necrotic damage and have resistance to radiant damage.
- Any creature that moves within 5 feet of you for the first time on a turn or ends its turn there takes 1d8 necrotic damage, and it can’t regain hit points until the start of your next turn.
- You can use your action to create a 10-foot-radius sphere of swirling death energy centered on a point you can see within 60 feet of you. Each creature in that area must make a Constitution saving throw. A creature takes 3d8 necrotic damage on a failed save, or half as much damage on a successful one. If a creature fails its save, it also can’t regain hit points until the start of your next turn.
