Magic Conduit

The you have learned to channel the full force of the Weave through your body, but at a great cost.

Your Overchannel ability now evolves into the Magic Conduit State. For the next 1 minute, you channel the full force of the Weave through your body. While in this state, you cannot be healed, by any means at all (including Boons). But in exchange, all spells you cast are considered to be 9th level (it still will consume the original spell slot), you can cast 2 leveled spells on your turn, all your spells that deal damage now deal maximum damage, and lastly all your spells can't be negated, suppressed, or countered during this duration. You can choose to end this state early as a Bonus Action. When this state ends, you gain 3 Levels of Exhaustion (ignores immunity) and are limited to spells up to 3rd level for 1 round. You can spend a 9th Level slot to enter this state again.
