You brandish the weapon used in the spell’s casting and make a melee attack with it against one creature within 5 feet of you. On a hit, the target suffers the weapon attack’s normal effects. Your attack also causes the withering effect - at the start of its next turn, the target takes half of the damage as necrotic damage.

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d8 necrotic damage to the target. Damage rolls increase by 1d8 at 11th level (2d8) and 17th level (3d8).
