As an action, make a weapon attack.

On a hit, add 1d10 + your spellcasting ability damage to the attack’s damage roll and the creature is bleeding 2.

On a critical hit, add twice as much damage.

On a miss by 4 or less, add half as much damage.

Augment

You can increase the damage by 2d10 and the bleeding level by 1 for each additional mana expended.
