Void Light

You summon a sphere of shimmering darkness that radiates eldritch energy, both illuminating and corrupting the area around it.

Effects:

1. Dark Illumination: You create a 20-foot-radius sphere of dim, shadowy light centered on a point you choose within range. The sphere moves with you, remaining centered on you. This light is not considered magical light for the purposes of dispelling or overcoming magical darkness.

2. Necrotic Radiance: Any creature of your choice that starts its turn within the sphere or enters it for the first time on a turn must make a Constitution saving throw. On a failed save, the creature takes 3d8 necrotic damage and has disadvantage on saving throws until the start of its next turn. On a successful save, the creature takes half as much damage and isn't affected by the disadvantage.

3. Healing Void: You and any allies within the sphere regain hit points equal to 1d8 + your spellcasting ability modifier at the start of each of your turns while you concentrate on this spell.
