Staff of Thunder and Lightning

You gain a +2 bonus to attack and damage rolls with this magic quarterstaff. Additionally, while holding it you can activate one of the following properties, each of which can be used once per dawn.

Lightning. When you make a successful melee attack with the staff, you deal an extra 2d6 lightning damage.

Thunder. When you make a successful melee attack with the staff, you cause it to emit a thunderclap audible up to 300 feet away. The target makes a DC 17 Constitution saving throw or it is stunned until the end of your next turn.

Lightning Strike. You can use an action to fire a 120 feet long and 5 foot wide line of lightning from the staff. Each creature in the area makes a DC 17 Dexterity saving throw , taking 9d6 lightning damage on a failure, or half damage on a success.

Thunderclap. You can use an action to create a thunderous roar audible up to 600 feet away. Each creature other than you within 60 feet makes a DC 17 Constitution saving throw or takes 2d6 thunder damage and becomes deafened for 1 minute. On a successful save, a creature takes half damage and isn’t deafened.

Thunder and Lightning. You can use an action to use the Lightning Strike and Thunderclap properties simultaneously. This doesn’t expend the daily uses of those properties, only this one.
