Dungeon suggestion!

[WaDaFack]

Unlike any other dungeon, this one, you MUST kill everything in room to move on to the next level. As every level passes, the harder the dungeon gets. Than, every 5th level, there's a boss. There would only be 5bosses, meaning 25 levels in total. Obviously, the first boss being easiest, and last boss being the hardest.
The main theme of this dungeon would be ancient greek gods, so pretty much, giants, gladiators, etc.

You are given the chance to get new items, but when you complete the dungeon, you are also given a prize of 100 000g! Don't think this dungeon will be easy to go through. You FOR sure need atleast 2-3 healers!

Thoughts?
