Kal's Radiance

4-level Abjuration

Bright light spreads within a 15-foot-radius sphere centered on a point you choose within range. The light spreads around corners, and it lasts until the spell ends.
When a creature moves into the spell's area for the first time on a turn or starts its turn there, that creature must succeed on a Constitution Save or take 6d6 radiant damage, or half damage on a success save. Additionally, that target is blinded for it's turn and emits a dim light in a 5-foot radius. This light makes it impossible for the creature to benefit from being invisible. The light caused by this spell go away when the spell ends. While a creature is in this sphere, their vision is reduced to 30ft if they're not blinded.
