Parasite of the will The Void

Make a Spellcast Roll against an adversary within Close range. Once per rest on a success, mark a Hit Point to Infect the target with a tiny magical bloodworm.

Presence Rolls against the Infected target have advantage. When the Infected target makes an attack roll, you can spend a Hope to give the roll disadvantage. The Infected condition lasts until you take a rest or you sacrifice the bloodworm to make the Infected target mark a Hit Point.
