Still loving this show. You've made me facepalm mroe than once, though, so here's some advice that should help you survive;
You should get Ass a crutch. Actually, you should get backpacks and armor for all your companions, and start hoarding crutches. Search in those (many, many) tombs you spotted north of the town you're currently in. Don't delve too deep obviously for fear of the inevitable mummy and its curse, but you can at least grab a lot of gear. If you do accidentally disturb the mummy, run and sneak back out and pray your friends are as smart as you are or at least didn't see the mummy or skeletons before you closed the door and started running. You'd want to have some serious skill before dealing with mummies because the curse directly reduces your skill rolls, so a skilled axeman would be acting as if they had adequate skill.
Dumping Ass' shield wasn't necessarily the best option, clearly, because she's not too good at dodging and is now missing a foot. Completely defenseless. It would be better for her to go around bashing people with a shield and deflecting blows than to crawl around and slash at their ankles while they bludgeon her to death.
Aim for the foot in combat to get your opponent on the ground. This slows them down significantly, reducing their danger to you, and thus puts the odds heavily in your favor for the remainder of the fight. Disarming them should be the next step, but it's important to get them on the ground first because even unarmed they have a good chance of insta-killing you with a punch or kick to the face, and once they're prone they get something close to a 50-70% speed reduction. Also remove and drop your own backpack before a fight to increase your own speed as much as possible. Just don't forget to pick it back up when you're done! You can technically look for it later, but that requires effort...
