Since Boreworms spawn was fixed - they become pretty high threat for players. I suggest some things to avoid them - they look like groboids from Tremor movie - and possible react on sounds, what if fur boots and bunny slippers sighnifically reduce their aggro radius, so we can lurk caves more freely? Would be nice and fun little thing.
any way to remove unneeded annoying stuff from game is good. Though plain "fur boots = no aggro from boreworms" seems pretty OP, so I've made this as alternative. (but we're not allowed to have nice things, so...)
