dont know what cap is set to, had gotten to lvl 27 before stopping, seems like the xp glitch only works with followers and works anytime to get an exploration xp bonus and the follower goes over it like you can walk back and forth in evelyn house and continue gaining xp, attributes maxed out at lvl 15 skills at lvl 5. again its only the followers giving the xp the 2 mains will not trigger after it has been obtained once, also if you get to the underground pirate cove and get beyond the skull blocking the path there is an exploration bonus that gives 17.5k each time if in not mistaken, or take off a zero but is the highest xp gain atm and is fairly easy to find the line that needs to be crossed to continue triggering. also it does work for each follower and in multiplayer so each person can continue running one and quicken the process
