Amaranthium (Magic: Hemomancy)

Amaranthium (Magic: Hemomancy) is the first of three Magic-themed DLC-like content sequels for the Amaranthium series, adding items such as Blood Vials, obtainable by defeating enemies with a Dagger.
Using JEI or REI is realy helpful, as Daggers are a bit, Weird to make, requireing Bloodstone, a new ore that spawns between Y1 and Y46, and requires an Iron Pickaxe to mine.
Focusing on the mods main function: Damage for reward, you can damage yourself to get things in return.
one example of this is the new keybind 'Conjure Blood Blade' upon pressing the keybind, C by default, You take a lot of damage and get a Blood Blade, a sword with few uses, but can be crafted into 10 blood vials when put next to a glass bottle in a crafting grid.
Blood Vials are a new Drink added to the game via this mod, and when drunk, you will gain Regeneration, max out on saturation, and become Nausiated because drinking blood is realisticly very gross.

Anyone who wants to make an addon for this mod can if they wish.
Enjoy ;)
