Here is what I found when testing things out:
I played Survival on the map, The Deeper Well on Massacre/Rifted until I reached wave 170 and had an idea! What if I started over on wave 99 and put the bonus difficulty on?! I knew I would probably get smashed but I tried anyway. So I started the map over on wave 99 with Massacre/Rifted/Lycan King Difficulty and managed to get to wave 106 before they were just too much!
The amount of Godly items dropped were very common, to the point where I was able to be picky. It dropped Godly items of all kinds from accessories to rifted armor
