Barrelsnap

Over the centuries, this netherese weapon has absorbed the cold of the Reghed Glacier, making every part but the handle icy to the touch. Attacks you make using this magical weapon deal an additional 1d4 cold damage with each hit. You have a +1 bonus to attack and damage rolls made with this weapon.

This icy whip has a revolving cylinder enchanted with Netherese runes. The cylinder has 4 slots housing an equal amount of magical cardridges. Cardridges are not consumed when they are fired, but they can be removed or swapped out. When you hit a creature, the cylider spins around, locking into a cardridge and firing it off. A fired cardridge produces one of the following effects (roll a d4):

1. The West's coolest. If the creature you hit with this weapon is not immune to cold damage, you inflict a biting chill, causing the creature to make a DC14 Constitution saving throw. On a failure, its speed becomes 0 until the start of your next turn. On a success, its speed is halved instead.
2. Red  breeze. If the creature is Large or smaller, it must make a DC14 Str saving throw or be knocked 10 ft. backwards by a gust of wind.
3. Snapgrab. If the creature is Large or smaller, it must make a DC14 Dex check or be grappled. If the target is a beast or a loose object that's Tiny or Small, the grapple automatically succeeds.
4. It's high noon. The target takes 2d10 additional piercing damage as a fiery, magical bullet is shot as the whip snaps. The whip then casts Compelled Duel on the target (DC14), as if you were concentrating on it.

Proficiency with a Whip allows you to add your proficiency bonus to the attack roll for any attack you make with it.
