Deep Dungeon random floor effects are a fun idea, but they could be more!

absolutely agree. I would love if you could be able to get a couple of Lost-Actions-Adjacent skills to chose from and then pick 2 for your run, transforming your build and the way you approach the floors ahead.
Unfortunately, the only thing CS3 is able to do semi-successfully is regurgitate previous content on the current expansion max level.

Square had the perfect opportunity to make something to do with Occult Crescent (or another field op) tie in with a deep dungeon, the player power systems there allow you to be so playful (with OC to a lesser extent, but having job abilities that would make sense in a deep dungeon!).
