Lightning Rod

ᛚᛁᚷᚻᛏᚾᛁᛜ᛫ᚱᛟᛞ

You attach a small orb of lightning to a creature you can see within range. Until the spell ends, whenever the creature is hit by a melee weapon attack for the first time on a turn, the orb pulsates with lightning, and that attack deals 1d8 extra lightning damage.

If the target drops to 0 hit points before this spell ends, the orb returns to you, and you can use a bonus action on your turn to affix the orb to a new creature you can see within range.

At Higher Levels. When you cast this spell using a slot of 4th level or higher, you can maintain your concentration on this spell for up to 1 hour.
