As two actions, you choose a point within 20 meters and cause psychic energy to explode there. Each creature in a sphere centered on that point must make a Will saving throw. This spell has no effect on a creature with an Intelligence of −4 or less.
On a failed save, a creature takes 7d6 psychic damage and has muddled thoughts until the end of its next turn. During that time, an affected creature rolls a d6 and subtracts the result from all its attack rolls and ability checks, as well as its saving throws to maintain concentration.
On a successful save, a creature takes half as much damage but doesn’t suffer from muddled thoughts.
You can increase the damage by 2d6 for each additional mana or psi expended.
You can expend 1 additional mana or psi to cast the spell as a a reaction, which you use when you are hit by an attack. It is centered on you, but does not affect you or creatures you designate.
