there are some good legendary farm routes in this section of the forum. u want to look for locations with many mobs such as elites, rares, bosses etc which have guaranteed loot. also look for goblins and destructibles, chests, corpses etc. there is no guarantee to find this ring or to craft it. its rng. so if u find it. u find it. if not, i guess keep on farming lol ^^ some items also help u in your farming, move ms, spawning packs and goblins etc. so have a look around and see what fits you bets :) sorry for late response, was busy ^^
