Yamato

Casting Time: 1 Action Range: 60 feet Components: V, S Duration: Instantaneous Description: You conjure a spear of pure shadow and hurl it toward a creature within range. The target must make a Dexterity saving throw. On a failed save, the creature takes 4d8 necrotic damage, and shadows cling to it, reducing its movement speed by 10 feet until the start of your next turn. On a successful save, the creature takes half as much damage and suffers no movement penalty. At higher levels, the damage increases by 1d8 for each spell level above 3rd.
