Binding Discipline

You brandish the weapon used in the spell's casting and make a melee attack against one creature within 5 feet of you. On hit, the target suffers the weapon attacks normal effects, dealing 1d4 force damage, and etherial bindings restrict the target's ability to cause harm till the start of your next turn. In response to the creature's next attack roll, they take force damage equal to your spellcasting ability modifier.

This spell's damage increases when you reach certain levels. At 5th level the melee attack deals an extra 1d4 force damage to the target on hit, and the force damage dealt to the creature for attacking increases to 1d4 + your spellcasting ability modifier. Boath damage rolls increase by 1d4 at 11th level (3d4 and 2d4) and 17th level (4d4 and 3d4).
