As an action, you mentally lash a creature that you can touch or see within 20 meters, assaulting its ego and debilitating its confidence. The creature must make a Will saving throw.
On a failure, it takes 3d6 psychic damage and has disadvantage on attack rolls and ability checks for the duration.
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.
The 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 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.
