They have, so maybe we can work something out. You didn't mention in your post that Lari was using coffins the ridge hounds went through, so I assumed you were pulling unused ones out of the walls.

How about this: Perhaps as Lari was running away, she trips into some of the coffins that the Ridge Hounds have pulled out and eaten the corpses out of. That would at least save her time taking them out of the holes. She can set up one barricade and try to keep moving. And if you don't want to just keep hiding in the coffins, I may be willing to let Lari pick up a memento from one of the many corpses in the catacombs. Some were once warriors you know...
