Twilight Conflux

You call forth a swirling vortex of twilight energy in the palm of your hand, where light and darkness clash in a powerful conflux. Choose a point you can see within range, where this volatile vortex erupts. All creatures within 30 feet of that point must make a Constitution saving throw or suffer one of the following effects depending on the light conditions in the area around them:

Bright Light. The conflux radiates with overwhelming brilliance. On a failed save, a creature takes 6d8 radiant damage and is blinded for 1 minute. On a successful save, a creature takes half damage and isn’t blinded. A blinded creature can reroll its saving throw at the end of each of its turns, ending the effect on a success.

Dim Light. The twilight energies achieve balance. On a failed save, a creature takes 5d8 radiant damage and 5d8 necrotic damage. On a successful save, it takes half damage.

Darkness. The conflux turns the darkness tangible. On a failed save, a creature takes 6d8 necrotic damage and is restrained for 1 minute. On a successful save, a creature takes half damage and isn’t restrained. A restrained creature can reroll its saving throw at the end of each of its turns, ending the effect on a success.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th. If the spell would deal multiple damage types, you choose which instances of damage to increase.
