Change spell

You change how a spell that a creature is casting behaves. Casting this spell while casting another spell with somatic components requires the use of both hands at the same time. You must have successfully altered that spell before or have had the spell in your list of known spells, otherwise, you must roll an arcana check against 15 to successfully recognize the spell, which does not count as an action. If the targeted spell can be altered, you may choose one of the two alteration methods:

Invert You alter the spell's damage types to that of their opposite: Fire & Ice; Necrotic & Radiant; Psychic & Force; Poison & Acid; Bludgeoning & Piercing; or Thunder & Lightning.

Distort You creatively alter the spell's integrity by changing its form: change the save type to that of its neighbors: Dexterity, Strength, and Constitution; Wisdom, Intelligence, and Charisma. The way you alter the spell's save requires changing how the spell inflicts its effects; if the caster is unable to describe how the spell has been altered in such a way, the alteration automatically fails. EX: Altering fireball to require a constitution save could mean changing it so that the targeted area's atmosphere becomes unbearably hot, and the targets risk heatstroke.
