Elemental Inversion

This spell creates a semi-transparent sigil that hangs in space in front of the caster. The next spell with an elemental aspect cast within the next minute has that elemental aspect reversed with its opposing element. All other features of the spell remain the same. A Fireball, for instance, will become an Iceball that explodes with cold damage in a 20' radius. The sigil then disappears and the spell ends.

The elemental opposites where this spell is concerned are

Fire <>Cold

Lightning<>Thunder

Acid<>Poison

Radiant<>Necrotic

Force<>Psychic
