Darkstaff

4th-level necromancy

Casting Time: 1 action

Range: Touch

Components: V, S, M (a quarterstaff)

Duration: Concentration, up to 1 minute

The material component you hold becomes imbued with life-stealing shadow. As part of casting this spell, you can make a melee attack with the weapon. For the duration, the weapon becomes magical and you can use your spellcasting ability instead of Strength for the attack and damage rolls of melee attacks using the quarterstaff. On a successful hit, the weapon does not deal bludgeoning damage, but instead deals 4d8 necrotic damage. You regain hit points equal to the amount of necrotic damage the staff deals. Until the spell ends, you can use your action to repeat the attack with the weapon. The spell ends if you let go of the weapon.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 4th.
