Baidan546's Locational Health

The mod reworks vanilla health into locational health, with eight body parts tracked separately, from the skull and torso through to both arms, legs and feet. The player's health is opened with the H key, which brings up an in-game screen showing each part. Losing health in a particular part brings negative effects, and the mod is inspired heavily by the First Aid mod for Forge.

Damage to an arm applies Weakness, and damage to a leg or foot applies Slowness. Effects stack by level as more of a category's parts are broken. The head and torso are the vital parts: if either reaches zero hit points, the player dies immediately. Low torso health brings Nausea and low head health brings Blindness, and those effects are disabled for a limited period after applying Morphine.

Natural regeneration is disabled under this system, so the player must use other types of healing. Bandage restores a small amount and Plaster restores more, both crafted with wool, and the Bandage Wrap recipe restores the most. Healing from these items is applied over time. The player's health updates as healing is added, and when other mods add health the player gains one heart, with the extra points assigned to a random body part. The mod is published for Fabric only, for 1.21.11, and is not open source.
