- "Pain, Agony, Suffering, Torment. When the Rune is invoked, even the earth shall resonate its anguish. Torment of the mind. Torment of the body. Torment of the soul. All will be made clear when the Circle is drawn."
After the Ultimate Circle is inscribed on the ground and the Rune explodes, all hostile creatures in the 50 ft. x 50 ft. area of effect take 30-100 HP damage. There is no saving throw.
This spell cannot be learnt. It can only be cast through the artifact Symbol of Torment.
There is a scroll of Rune of Torment in the game files, but not in game. It might have been intended to be a learnable spell.
