The Blooded.jar

Warning: This mod may alter your game mode, modify your world settings, and access your in-game name. Additionally, this is a horror mod; if you are sensitive to such content, it is recommended that you do not play it. By playing this mod, you acknowledge that you are not sensitive to such content.

The mod is still under development; I previously encountered crashing issues related to performance mods, but I’ve fixed them. Here’s what you need to know about the mod: "The Blooded.jar" can open doors, teleport right next to you when you least expect it, send messages in chat, delete items from your inventory or add new ones, detect if you are cheating, disable commands like KeepInventory, change your game mode, and inflict effects such as blindness or nausea, you can't kill it with a sword; try something else ;)
