As an action, a creature that you can touch or see within 18 meters must make a Reflex saving throw.
On a failed save, a writhing mass of thorny vines wrap around it as it is restrained.
A creature restrained by the vines or one that can touch the creature can use an action to make an Acrobatics or Brawn check (its choice) against your spell save DC.
On a success, the target is freed.
You can expend 1 additional mana or psi so while restrained by this spell, the target takes 3d6 piercing damage at the start of each of its turns. The damage increases by 3d6 for each additional mana or psi expended.
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.
