Dark Scripture

Darkness spills from your mouth as you evoke a dark boon that grants a target that you can see with an additional 1d10 to that person's next damage roll from any attack. You must target an ally that you can empower and an ally to take away that amount rolled from their hit points.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 for each slot level above 1st.
