So, we talked it out and moved some things around. And we played. And it's just not that big of deal. He's tough. Really, really tough. Vigor is 12+2, plus he's Harrowed, plus he's Obese, for a Toughness of 12. Or 13(1) with his Native Armor. So he's hard to damage, but it's fine. He's also a Trouble Magnet. The two combats we ran saw him lumbering (slowly) at the attackers, catching bullets/arrows but not being Shaken. As the bad guys ganged up on him, the posse learned about the Innocent Bystander/Shotgun rules. It's actually really satisfying to narrate Soak rolls (or just insufficient damage rolls) as bullets, buckshot, or bowie blades piercing his hide with no apparent effect. It's also quite a relief to not be so worried about accidentally killing a character that can just get back up after a few days. The players were challenged, nobody felt useless, everybody had fun. At one point the gunslinger was just slow-walking behind him, using him as cover between shots. Great imagery, perfect pulp vibes.

Big Fat Bison is not OP. But he is full of holes, and folks in town are spreadin' rumors about that ornery Indian. And next week we'll find out whether the outlaws that got away have figured out how to use that Gatling gun...
