Darkness Blade Arc
3rd-level evocation (brandish) (Paladin, Sorcerer, Warlock, Wizard)
- Casting Time: 1 action
- Range: Self (30-foot line)
- Components: V, M (a melee weapon)
- Duration: Instantaneous
As part of the action used to cast this spell, you swing a melee weapon. An arc of pitch-black energy is traced in the air by the weapon’s path, and the arc launches outward, threatening creatures and objects in a 5-foot wide, 30-foot line. Every creature in the line must make a Dexterity saving throw. On a failed save, a creature takes 5d8 necrotic damage, and is necrotized until the start of your next turn. A creature takes half damage on a successful save.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you increase the damage by 1d8 for each slot level higher than 3rd.
