You summon a radiant halo of yellow lightning behind your back, encircled by five hollow, four-pointed stars of crackling lightning. While the spell is active, when a creature moves into or within a range of 30 feet of you for the first time on a turn, you can use your reaction to unleash a bolt of lightning from one of the star nodes, when you do so that star is expended.
Make a ranged spell attack against the triggering creature. On a hit, the target takes 5d8 lightning damage.
Once all five stars have been expended, the spell ends early.
At higher levels: When you cast this spell using a spell slot of 5th level or higher, you summon one additional lightning star for each slot level above 4th.
