Endless Abyss

Charge up your spell for 2 rounds. Once released, covers the whole battlefield in an endless, dark abyss. Allies & the caster will not be affected. The enemies will not be able to see you, but you can see them. They will shine with a bright, red light. This will last until dispelled. If the enemies want to try to see a select ally, they must try a wisdom saving throw of d20. They must get an 18 or higher.
