Bleed

You slash at the air in front of you and a jagged cut appears on a target within range. The target takes 1d8 necrotic damage when it is cut and must make a Constitution saving throw or suffer a magical wound which causes a further 1d8 necrotic damage each time it moves or takes an action. This damage ignores resistances. If the target has no blood to lose or the DM rules it would be ineffective this further damage does nothing.

At higher levels. When you cast this spell at higher levels the damage of all instances increases by 1d8 for each level above 2nd.
