Blood Rite: Rite of Siphoning

As an action, you can invoke this Rite and force one creature you touch to make a Charisma saving throw. On a failed save, the creature takes necrotic damage equal to two rolls of your Rite Die, and you gain temporary hit points equal to the necrotic damage taken by the creature.

Empowered Siphoning. The necrotic damage from this Rite is treated as the maximum possible amount instead of rolling.
