Electricify

Choose up to 3 weapons within sight. Muttering some words while holding your hands up, sparks of electricity are conjured and begin to imbue them with electrifying power. When this weapon does damage in any way, it deals an 1d4 lightning damage. Additionally, any lightning damage done by any of these weapons can hit another creature within 30 feet with the same amount of lightning damage halved.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the number of weapons that can be affected by this increases by one for each slot level above 3rd.
