Delerium Blast (TP)

When you cast this spell, you gain one level of contamination. You ignite arcane energies stored inside a delerium fragment held in your hand, and hurl it towards a space you can see within range. It explodes in a 20-foot-radius sphere of erratic psychic energy that overwhelms the minds and senses of those within. Each creature in the sphere must succeed on an Intelligence saving throw. On a failed save, a creature takes (10d6) psychic damage and becomes incapacitated until the end of their next turn. On a successful save, a target takes half as much damage and suffers none of the spell's other effects.
