Vestige of King Elidyr

You unleash the rage of King Elidyr, striking your enemies with the force of a dozen warriors. Make a ranged spell attack against the target. On a hit, the target takes 2d8 force damage, and targets must succeed on a DC 12 Strength saving throw or be knocked prone.

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