As two actions, a creature that you can touch or see within 10 meters must succeed on a Will saving throw or be stunned 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 or psi expended. The creatures must be within 5 meters of each other when you target them.
You can expend 1 additional mana or psi so the creature is paralyzed instead of stunned.
