Cloudpierce

Lightning crackles from your fingertips, coursing through and imbuing your held weapon with newfound power. For the duration of the spell, this weapon deals an additional 2d6 lightning damage on a hit. In addition, when you use the weapon to attack a target that is within 5ft of at least one of its allies, you make the attack roll with advantage.

While concentrating on this spell, you may use the attack action to hurl lightning from your weapon (range 30ft) at a creature, rolling normally and dealing 2d6 lightning damage. Until the start of your next turn, your weapon is drained of this spell's effects.

At Higher Levels. When you cast this spell using a 3rd- or 4th-level spell slot, the damage increases to 3d6. When you cast it using a 5th- or 6th-level spell slot, the damage increases to 4d6. When you cast it using a spell slot of 7th level or higher, the damage increases to 5d6.
