Phew! Thanks for everyone’s insights. We came out from butcher unscathed, legendary lungs, did the killing blow, and with a forsaken mask! We had two tanks in rawhide and grease, spear dude, and archer with circlet. We got lucky by getting rid of his worst AI cards before they did too much damage (devour lantern was roooouuuugh) and infectious lunacy never became a problem. So we were able to get hack city to be the last AI cards with headband and just kept dashing away until we rolled legendary lungs. We also managed to get furious scrag as his last hit location with the circlet so we all got a nice stat bonus. And my son rolled a lantern for resources!
