Blazing Reflector

When you cast Blazing Reflector, you take 1d4 fire damage per damage dice of the attack you're reacting to and all attacks or spells that would hit you during the duration instead are reflected by a flaming sphere around you. Instead of you being hit, instead the enemy takes one half the damage of fire or force damage (casters choice). For each spell slot above 4th, the Blazing Reflector lasts two extra rounds. If cast with a 9th level spell slot each creature within 10 feet must make a dexterity save against the casters save DC, on a success they take full damage but stay where they are. On a fail, they also take full damage but are pushed back 10 feet and knocked prone (this can provoke opportunity attacks).
