As an action, you pull magical energy out of a creature that you can touch or see within 10 meters. The creature must make a Will saving throw. If the creature doesn’t have mana or ki, the spell has no effect on it.

On a failure, it takes 1d10 force damage, loses 1 mana or 2 ki, and has disadvantage on saving throws to maintain concentration on a spell until the end of its next turn.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

If the creature has innate spellcasting with a set amount each day, use the highest level slot from that section to determine if the slot is lost.

Augment

• You can increase the damage by 3d10 and the target loses 1 additional mana for each additional mana expended.

• Antimagic Rebuke. You can expend 1 additional mana to cast the spell as a reaction, which you use when a creature that you can touch or see within 5 meters of you succeeds on a saving throw against a spell. The spellcaster is the target, the damage changes to 1d6, and additional augments increase the damage by 2d6 instead of the normal increase.
