Basic landscape mobs' stealth detection also scales up significantly starting in Moria. Any +stealth level boost, be it from trait, tools, pocket, or cloak, will return you to the type of mob behavior you experienced up until that point. You don't need a lot, just one +2 boost will do it. We had some discussion on this back in the early days of Moria, and lots of the burgs who were accustomed to stealthy camp infiltration for a quick boss kill, or even simply trying to get up for a position surprise strike, were experiencing the same.
