This mod aims to make the underground more interesting.
Features
Suspicious shrines
Enchanting altars
Rousing riddles
Tormenting traps
Collapsing caverns
Fungal Flora
By default, these secrets are now quite rare close to the surface, but you can modify the config.json file to change that.
For more detailed information (i.e. spoilers), I've created an article with all the information on the mod.
This is a work-in-progress and there may be bugs.
I recommend that you install Treasure Chests Expanded to allow for more modular rewards.
