Sorcerer/Witch/Wizard (Evocation)

The spellcaster’s eyes blaze with unbearable radiance, casting light as strong as the noon-day sun in a 20-foot cone and torch-bright illumination extending 30 feet further. Creatures within the illuminated area must succeed a Wisdom saving throw or be blinded for 1d4 rounds. Undead and fiendish creatures have Disadvantage on their saving throws and suffer 1d8 damage every round they remain within the light.

The reverse of solar glare, abyssal gaze, turns the spellcaster’s eyes into seemingly bottomless pools of utter black. A creature within 20 feet of the spellcaster that can see and be seen by the caster must succeed a Wisdom saving throw or become transfixed by the terrible darkness, unable to act. Every subsequent round, a creature stricken by the abyssal gaze can attempt a new saving throw to shake off the effect. Undead creatures had Advantage on their saving throws and fiendish creatures are immune. Once a creature has succeeded a saving throw, they cannot be affected by this spell again for 24 hours.

Both versions of the spell can be sustained for 1 round per caster level.
