The Mongoose Mountain Gang

A gang styled after the Old West, replete with unshaven dirtbags and violent wretches. Mostly human. They travel everywhere as a pack, taking meals together, going to bed together, even bathing (rarely) and whoring (often) in a group.

They use the bandit stat block with the following additional abilities:

Bump & Grab: The MMG bandit can use an action to target a creature that has been hit by or grappled by another bandit since the end of its last turn and make a Dex (Sleight of Hand) check vs the target's Str saving throw. If successful the bandit grabs a held item from the target, such as a weapon, shield, or spellcasting focus. If the target holds nothing the bandit grabs a loosely-secured item from their belt or pack instead, like a water canteen, a purse, or belt pouch.

Brotherly Love: A MMG bandit can use a reaction to redirect an attack against an adjacent ally to itself, taking the hit instead. This is used after a target is declared, but before the attack is rolled.

MMG bandits usually gather around their targets and alternate using Dodge (and Brotherly Love) and attacking, with a few spares using Bump & Grab starting on the second round.
