Balance item chests

[VisMortis]

Feels pretty unrewarding beating a cyan boss, example 5 star spider and get a normal treasure chest.

When beating 5 star tree gives you always a giant chest.

Also never got any rarity item besides from the skulls or the vendor delta chest.

I dont think this is intended?

I'm not sure if cyan levels have increased giant/omega drop rates but it doesn't seem like it. I was expecting guaranteed giant chests at some point but nope. Why spend the extra time when I can just steamroll on 4* for the same loot?

Cyan bosses don't drop Humble Treasures and the chance to drop Omega or Delta goes up with each star, linearly.

4* doesn't drop Humble Treasures, can be cleared faster, and you can get giant/omega chests.
