As an action, your poison slows the processing and reaction time of a creature that you can touch or see within 10 meters. The creature must succeed on a Fortitude saving throw against poison 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 one additional creature 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.
