As an action, darkness spreads from a point you choose within 35 meters to fill a sphere for the duration. The darkness spreads around corners.
If any of this spell’s area overlaps with an area of light created by a spell using equal or less mana, the spell that created the light is dispelled.
Shrieks, gibbering, and mad laughter can be heard within the sphere. Whenever a creature starts its turn in the sphere, it must make a Will saving throw, taking 2d4 psychic damage on a failed save, or half as much damage on a successful one.
You can increase the damage by 1d4 for each additional mana or psi expended.
You can expend 1 additional mana or psi so the darkness is magical. A creature with darkvision can’t see through this darkness. Non-magical light, as well as light created by spells of using equal or less mana, can’t illuminate the area.
