Arcane Mark (Pain)

You blaze an arcane rune onto a target’s body. Make a ranged spell attack. On a hit, the rune appears and pulses with magical energy. The next time you strike the target with a melee weapon, the rune releases the energy dealing 1d6 points of Force Damage and ending the spell. If the target is not struck within 1 minute, the rune fades. Although the spell does not require concentration, only one arcane mark can be active at a time. 

The damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
