So I know some people who do this, and I’m pretty sure that if this isn’t a bug, it’s not intentional. You can do the south path, fight the boss and it kicks you out. You then run to middle lane and stand just outside of the vine wall and when the boss dies, you get credit and the loot to go with having beaten the mini boss. So like if your lane kills the boss you get two chests doing it. But everyone else’s lane gets only one chest. This way you can circumvent it and get a total of 6 chests, two from each mini boss
