NightBlood is a sword featured in fantasy books written by Brandon Sanderson. In the books, the sword is alive and incredibly powerful, but rapidly drains the energy of the wielder.
In this mod, you can craft NightBlood with a Netherite sword surrounded by Bottles of Enchanting. This sword will do tremendous damage but drains XP and then health when held, and is intended as a powerful late-game continuation of the vanilla weapon upgrade path.
