Hmm the distance filter is an interesting idea actually. It would require some changes with how it works, but its definitely possible. And the bury and alch options are necessary features, I agree, I will start working on those very soon.
I dont think it will work like that. It would still choose other safespots that arent prioritised often enough that it wouldnt be worth it. And even if it attacked wyverns in the area, they would still walk over to your character and no longer be the required distance.
