Cursebite

Cursebite is a necrotic invocation used by warlocks, particularly those of the dark pact. Cursebite takes advantage of a warlock's ability to curse their foes and each creature so cursed within an area of fifty feet in radius can become affected with cursebite, which strikes deep into their life force. Though cursebite relies primarily on a warlock's charisma for power, dark pact warlocks with a high enough intellect cast cursebite with even greater lethality. Cursebite is a somewhat complex spell, and requires its caster to rest briefly before casting it again.
