Surprised I never saw this thread before until now. Thank you for resurrecting this thread Pearlie Hallow.
I think the Marble Biome, Floating Islands Hallow (mainly surface) could use more features. Hallow because of what Xylia said:
And Marble because there's only 2 Enemies there. One which is almost universally hated by every player making it unpleasant to explore, and Marble blocks aren't renewable like Granite Blocks are. Perhaps adding 1 or 2 more Greek related enemies with unique new items or special items in Marble House Chests could make the Marble more fun to Explore. Along with possibly having Granite/Marble Biomes spawn bigger than current on Medium/Large Maps.
There are other Biomes like the Ocean, Floating Islands, and Underworld which I also think could use more features though how I think they can be improved has been suggested in many other threads by others and myself a lot so I won't go into those here.
Well, there are only 2 enemies in Granite too. One of them has the capability to kill you in Expert Mode, just as badly as Medusae can (projectile reflect sucks when you're using weapons like Meowmere, for example) though admittedly, the chance a golem will put his dukes up at just the right time to screw you over is a lot more rare than a Medusa stoning you in mid-air or some-such, but still.
Either way, neither Granite nor Marble has anything special in their chests, but you do have a point that Marble is not renewable (it should be). Perhaps have the Hoplites drop Marble Blocks upon death would help?
I'd be all up for giving Granite and Marble a unique item that spawns in their respective chests, but I don't really have any ideas what those could be, perhaps they could be items that mitigate each other's deadliness? Granite could have an item that resists stone (3 second debuff instead of 6 and cuts fall damage in half while stoned) and Marble could have an item that cuts Reflected Damage in half.
