As an action, you can unleash a stream of water that drains and heals life forces. Choose one of the following options.

Ebb. Life ebbs from a creature that you can touch or see within 10 meters. The creature must make a Fortitude saving throw.

On a critical success, it takes no damage.

A willing creature within 5 meters of the target can regain health equal to half the amount of necrotic damage dealt.
