As two actions, a creature that you can touch or see within 18 meters must make a Fortitude saving throw.
On a failed save, it takes 5d8 cold damage and is stunned for the duration.
On a successful save, it takes half as much damage and isn’t stunned.
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 increase the damage by 6d8 for each additional mana or psi expended. If this spell is augmented to target additional creatures, this damage is halved.
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.
