Eldritch Crash

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise the spell fails.

On a hit, the target suffers the attack's normal effects, and it becomes sheathed in a blue crackling energy, dealing 1d8 force damage and causing the enemy to have disadvantage on spell saves from the spellcaster until the end of the next turn.

At 5th level, the melee attack deals an extra 1d8 physical damage to the target, and 1d8 force damage. Both damage rolls increase by 1d8 at 11th level and 17th level. Also at 11th level the element of Eldritch Pierce can be changed to an element the spellcaster wishes but can only be changed out every short rest. If the spell itself isn't changed out during said short rest it becomes force damage once again.
