Evengard's Lightning Blast

A large streak of yellow electricity zips towards a creature and zaps them for 1d6 lightning damage. If there is another creature within 20 feet of the target they take half of the same damage (choosing the closest one if there are multiple) which repeats the attack as if that creature were the initial target until the spell has hit a number of additional targets equal to your spellcasting ability modifier (you can choose which targets not to hit) or until the damage becomes less than 1. This spell can hit the same creature multiple times.

The spell deals 1d6 additional damage at higher levels: 2d6 at 5th level, 3d6 at 11th level, and 4d6 at 17th level.
