Blood Lance

You conjure a lance made from blood forming a line 60 feet long and 5 feet wide out from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 3d10 damage on a failed save, or half as much damage on a successful one. You can use either your own blood, or that of someone else. When using your own blood, you take 1d10 necrotic damage to conjure the lance. If there is a corpse or a willing creature within 5 feet of you, the damage can be transferred to them instead (corpses won't take damage).
