As an action, you can stiffen the blood of a creature that you can touch or see within 18 meters. The target must make a Fortitude saving throw. A creature isn’t affected by this spell if it doesn’t have blood in its body.
On a failed save, the target is 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 9 meters of each other when you target them.
You can expend 1 additional mana or psi so the creature is paralyzed instead of stunned.
