Mantle

Mantle provides shared code used by Slime Knights mods, including descriptive books and common inventories. It is available for Forge and NeoForge across Minecraft versions 1.7.10–1.20.1.

It also reworks the health display, overlaying colored hearts instead of stacking rows when maximum health is increased; ordinary hearts stay unchanged. Rent your own Minecraft server and install Mantle with one click from the panel to supply the shared code your dependent mods use.
