Cones of protection

Give all of your party cones of protection, lowering their vision capabilities but increasing their defense. They gain disadvantage on all ability checks, saving throws and attack rolls that would be affected by vision until the spell is dispelled, and also gain +3 to their armor class. You may dispel on your turn only. If used at a third level or higher spell slot, it gives 1 extra armor class per level up to a maximum of +6.
