Super: Arc Staff

As an action, you can summon and wield a magical lightning staff.

You conjure and equip a large staff coated in powerful lightning. You are proficient with this staff, have a +4 bonus to attack rolls with it, and can make attacks with it to deal 6d6 lightning damage.

Additionally, while this staff is equipped, when a creature makes an attack roll against you, you can use your reaction to deal 6d6 lightning damage to that creature, regardless of whether or not it's attack was successful.

The staff remains for a number of turns equal to your proficiency bonus.

You can't use this feature again until you finish a long rest.
