About this Mod
Adds a fully toggleable Hardcore system to any non‑Hardcore world.
This mod introduces the /onelife command, letting you switch players into or out of Hardcore on the fly without restarting the world.
It also includes several custom items that let you:
remove the OneLife curse
revive eliminated players
grant new OneLife status to others
If you want players to craft the OneLife Sword, make sure to enable the gamerule:
/gamerule CanCraftSword true
Enjoy the chaos — responsibly.

OneLife server crashes on startup – what to do?
Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.
Is OneLife compatible with forge?
OneLife officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with OneLife – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if OneLife consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
