As two actions, you brutally crush the mental essence of a creature that you can touch or see within 10 meters, debilitating its acumen. The creature must make a Will saving throw.
On a failure, it takes 1d6 psychic damage and is stunned until the end of its next turn.
On a critical failure, it takes twice as much damage.
On a success, it takes half as much damage.
On a critical success, it takes no damage.
If it has a head and is killed by this damage, its head explodes.
You can increase the damage by 4d6 for each additional mana expended. If this spell is augmented to target additional creatures, this damage is halved.
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 spell deals no damage, but 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.
