FirstAid

What FirstAid changes about health and healing FirstAid removes the single vanilla health bar and replaces it with eight separate regions: head, body, legs, and feet each get their own health pool. When you take damage, only the armor on the hit region counts toward protection. Helmet and chestplate values are multiplied by a factor so they remain effective despite their lower base armor. Vanilla natural regeneration is disabled by default and stays disabled even if you uninstall the mod unless you re-enable it in the config or with the gamerule naturalRegeneration true. Healing works through bandages and plaster. Right-clicking either item opens a small GUI where you pick which region to treat. You die instantly if head or body health reaches zero. ## Debuffs tied to limb damage Damaged limbs apply constant debuffs until healed. Feet damage gives slowness. Severe head damage triggers blindness and nausea for a short time. Morphine suppresses all health debuffs while active; when the effect ends the constant debuffs return. ## Armor calculation per region Armor only protects the region that takes the hit. A hit to the legs checks only your leggings. Because helmet and chestplate armor values are lower than a full chestplate, the mod multiplies them so head and body protection stays meaningful. ## Who this mod suits Players who want a more granular survival experience where positioning, armor coverage, and targeted healing matter. It works best when you're comfortable managing extra UI and configuring the regeneration gamerule. ## Compatibility and requirements The mod runs on Forge and Neoforge. Supported Minecraft versions are 1.16.5, 1.18.2, 1.19.2, 1.19.3, 1.19.4, and 1.20.1. Both client and server must have the mod installed.
