No, I’m not talking about your rank stench coming off of the corpses of the last mammoth bird you chowed down (those squiddy morsels…), I’m talking about spamming the smell button when hunters are near.
Every monster makes a clearly audible and distinct smelling noise when they smell that is easy to pick up if within 25 meters (in which case, hunters are close enough for you to see keep tabs on them anyway). About half of the sneaking monsters I run into, regardless of level, spam the smell button when hiding that I can just run past the sound cue and throw the dome without fail.
Just a tip from a trapper/medic and fellow monster player, smell constantly when hunting or at a distance from hunters. When you’re hiding in a bush, either they’re going to find you or they’re not, don’t worsen your chances by broadcasting your location to the hunters.
