Deflect Magic

Using your strength you attempt to overpower the caster you cause a contested roll using both of your spellcasting ability modifier. If you succeed you deflect the spell and it does no damage. If you fail the spell hits. If you succeed or fail by more than 5, you either direct the spell back at the caster (requiring you to make a spell attack) or it deals 1.5 damage respectfully.

For every level lower this spell is compared to the incoming spell, add -5 to your roll
