As an action, you freeze the veins of up to two creatures that you can touch or see within 10 meters and within 5 meters of each other. Each target must succeed on a Fortitude saving throw or be slowed 1 for the duration.
A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
You can target two additional creatures for each additional mana expended. The creatures must be within 5 meters of each other when you target them.
You can expend 1 additional mana to increase the slowed level by 1.
