Dance of the Twins

You tap into the duality of a single creature within range, manipulating its threads of existence. The target must make a Wisdom saving throw. The target takes 2d8+1d6 damage on a failed save, or half as much on a successful one. If the d6 rolls a 1, 3, or 6, the damage is necrotic, otherwise the damage is radiant. In addition, if two of the d8s roll the same number, an additional effect happens, depending on the damage type:

• If the damage was radiant, the target takes an additional 2d8 radiant damage. If they failed their save, they are also blinded until the start of your next turn as light pours from its eyes.
• If the damage was necrotic, the target takes an additional 2d8 necrotic damage. If they failed their save, they are also frightened of you until the start of your next turn as shadows dance across its body.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the spell does an additional 1d8 damage for each slot above 1st.
