While raging, you can use a bonus action to emit an electric aura. Creatures within 5 feet of you take 1d6 lightning damage at the start of your turn. Additionally, Once per day, you can use an action to cast Thunderwave (save DC 14).

Notes: This rough-hewn amulet contains a shard of lightning trapped in a transparent crystal. The amulet hums faintly when the wearer rages., Buff, Jewelry
