Chaotic Caster

You have a gambling side to you, and have discovered new ways to help you out in combat.

• Anytime you cast a spell that requires a DC, before you roll you can cast Chaotic Caster.
• Whenever cast you roll your DC to hit normally, but roll another D20, if the dice lands on 1-10 the spell collapses in on itself and does half damage to the caster. If the dice lands on 11-20 the spell gains a charge and does double damage.
• If on a crit, the half damage done to yourself turns into full damage. If you crit on an enemy 4x damage is dealt
