If a character critically fails when casting a spell, or fails normally when casting either an unconventional spell or any spell with a spell level above their Spellcasting Level in the corresponding school, then they suffer a Magical Backfire. A Magical Backfire is an uncontrolled, and often harmful, consequence of incorrectly manipulating unfamiliar magic. Find the table corresponding to the backfired spell’s school in the Magical Mishaps section, roll a d4, and add the spell level to the result of the roll.
