Thunder Cannon (5e Equipment)

Weapon (musket), rare

Not quite a musket, the Thunder Cannon more resembles a staff that resembles a musket. Regardless, the brass barrel and grandeous handle is a sight to behold.

The Thunder Cannon does not require ammuntion to fire. Additionally, when you make a ranged attack with the Thunder Cannon, every creature within a 40 foot cone of where you fired must make a DC 14 Constitution saving throw, or take 2d4 thunder damage and be deafened until the start of your next turn. A creature cannot be forced to make this saving throw more than once per turn.
