Destructive Teleport

This spell allows you and up to two willing creatures to teleport as many times as you want, up to 90 feet, to any unoccupied space within sight. Upon one of these teleports, you can choose to emit a massive wave of energy. If a creature within a 10 foot square fails a Constitution saving throw they take 20d6 + spell casting modifier force damage, being pushed backwards 1d6 x 5 feet, or half as much damage on a success and are not pushed back.
