Bellepheron's Lightning Leap

Shrouded in magic lightning, you teleport to an unoccupied space within a number of feet equal to half your movement speed. Immediately after you appear, your shroud explodes, and each creature within 5 feet of the space you arrive at must make a Dexterity saving throw, taking 1d10 lightning damage on a failed save, or half as much damage on a successful one.

Additionally, the weapon used in the spell's casting is temporarily imbued with some of the spell's power. The next time you hit a creature using the imbued weapon during the spell’s duration, the attack deals an extra 1d10 lightning damage. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the lightning damage increases by 1d10 for each slot level above 1st (to a maximum of 6d10).
