So, after hours of breeding monsters on my first level of apartments, I was able to kill the Legendary Hero.. Which was the end of the game. I didn't realize he was the end boss, I wanted to kill him since he attacked us and keep playing with the same monsters I've been breeding for so long. (I did save right before I upgraded the second level)
To do this, do I just let him walk on in to my Devils Tent and keep playing? It really threw me off and was kind of weird to have the credit roll and all that. Will he take stuff from me when he comes after later upgrades?
