Arcane Punch

You punch an enemy with a blue, arcane-infused fist for 6d8 force damage. On a hit, the enemy gets knocked prone for one turn.

You have the option to turn the spell into a concentration spell by holding an action to charge it up, adding another 3d8 damage and turning the blue energy around your fist red/orange. This "supercharged" punch knocks the enemy back 30ft.

At Level 4+

At level four, you unlock the ability to attack once with each fist (if both hits succeed, the second hit knocks the enemy prone). YOU CAN ONLY SUPERCHARGE ONE FIST.

Every level past 4 adds 2d8 damage all around.
