Audacious Potential

You can tap into your wellspring of magic capacity to unleash devastating attacks at your own expense.

You gain the following benefit:
• Once per long rest, you can cast an Evocation spell at 2 levels higher than your maximum spell slot level.
• The spell must be able to cast at higher spell slot levels. The raised spell level cannot go higher than a 7th level spell slot.
• You take 30% of the damage dealt by the attack.
