You can cast two spells at once.
Benefit: You can cast two spells at the same time, and they go off at the same time. The cast time for both spells to go off is equal to the longest casting time of either spell.
Each twincast spell uses up a spell slot two levels higher than the spell’s actual level. Twincast Spells can be prepared separately and then matched on the spot. You can only cast a twincast spell with another twincast spell, however.
