Will Charge

 You can channel your will into a weapon for a short period, infusing strikes with arcane might. The first time you hit with a melee weapon attack during this spell’s duration, the attack deals an extra 2d8 force damage to the target.

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