As two actions, you freeze a creature that you can touch or see within 10 meters. The creature must make a Will saving throw.
On a failure, it is stunned until the end of its next turn.
Augment
You can augment this spell with the following options, expending mana for each option.
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 2 additional mana so the duration changes to 1 minute/mana, concentration and the creature 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 expend 1 additional mana so the creature is paralyzed instead of stunned.
