Grey Health
by inknat
Grey Health adds a second health bar to NeoForge 1.21.1 that limits how much natural regeneration can restore, so most damage must be healed with external sources.
What it does
Grey Health tracks a grey bar alongside the normal health bar. Whenever a player takes damage, the grey bar drops by a share that depends on the damage type, and the share is set per type through a datamap. Falling and drowning deal no grey damage by default, explosions and lava deal 100%, and other damage sources deal 50%. Values can be changed in the config file.
Natural regeneration restores only the normal bar, and the grey bar is restored only by external healing such as potions, golden apples and modded healing items. Requires no additional mods beyond NeoForge. Open source under the MIT License, the mod is published for 1.21.1 only, with the latest NeoForge file dated 2026-09-23 as version 1.1.
Key features
Grey health bar
A second bar shows the portion of health that natural regeneration cannot restore on its own.
Damage type ratios
Each damage type maps to a grey damage percentage, set by default in a datamap and adjustable in the config file.
External-only restoration
Potions, golden apples and modded healing items restore the grey bar, while natural regeneration does not.
Default damage values
Falling and drowning deal no grey damage, explosions and lava deal the full amount, and other sources deal half.

Use cases
Hardcore survival
Players who want healing to depend on items rather than time can use the grey bar to slow natural recovery.
Modded healing items
Healing items added by other mods restore grey health, so custom food and potions fit into the same system.
Who it’s for: Players and server owners who want natural regeneration limited, and who are comfortable adjusting damage ratios in a config file or datamap.

What the author says
This mod adds a second healthbar to the game, known as grey health, which nerfs java's famously powerful natural regeneration by capping it. Whenever a player takes damage, their grey health is reduced proportionally depending on the damage type.
