A mod that adds exploration-based Heart and Stamina Container upgrades.
This is not a Stamina mod, if this mod doesn't find a suitable Stamina mod installed the Stamina items and blocks of the mod don't get generated. So you can use it as your regular Heart mod if you wish.
This mod handles health and stamina upgrades via modifiers, so, it's hopefully compatible with most mods that also alter these values.
The containers are crafted with their respective shards that have a configurable probability to generate in every loot chest (Even from other mods). They can also be obtained by mining Crystals that generate in caves and some dimensions:

The crafting recipes are the following:

To avoid making the shards useless in the late game, every time the player dies it loses a part of the health and stamina gained with containers (Configurable).
Currently it's compatible with the following Stamina mods:
If the mod becomes popular I'll consider adding compat with other Stamina mods.
The mod is fully configurable via the Mod Menu.

With the default configuration:
I made this mod to have a painfully configurable Heart mod to use in a Modpack I'll release in the future (I hope you look forward to it).
