Because from the ability description: Elven archer, dog, and another partner. It looks like they can completely remove the danger level of the world by constantly refreshing the map.
Well... you can’t completely turn it off the world danger mechanic and I also noticed that the less danger world lvl is the fewer things you can find and you know... at Lona lvl 50+ I personally only worried about bandits because they are soooo randomly appear + they have a lot of DEF stat and SUR stat + they are really fast + they can easily stun and kill you even at 50+ lvl especially if you have 100% world danger and if you play on Hell+ difficulty (you can’t escape while you’re in the fight).
