@superspartan177 there's an old classic story from China abouts a couple of husband and wife. So, whenever the husband would go out for a long trip the wife always told him to wear green hat as a sign to her lover that her husband is away.
@criver that's because monster is highly territorial and most of them resides in the labyrinth and the stronger they are the deeper their nest is, so only weaker monster go out of the great labyrinth
