As an action, the eyes or ears of a creature that you can touch or see within 10 meters tear free from its head and scurry away. The creature must make a Fortitude saving throw.

On a failure, it takes 2d6 necrotic damage and is blinded or deafened (your choice) for the duration.

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.

The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Augment

You can increase the damage by 4d6 for each additional mana expended.
