Nether Weapon
Level 4 · Enchantment · Ritual · Concentration
You whisper in Void Speech and touch a weapon. Until the spell ends, the weapon turns black, becomes magical if it wasn’t before, and deals 2d6 necrotic damage (in addition to its normal damage) on a successful hit. A creature that takes necrotic damage from the enchanted weapon can’t regain hit points until the start of your next turn.
