DuoPlugin
Life link plugin. Links you and a friends health, potion effects, and saturation. 1.20.x - 1.21.x. Originally made for an event. I am shaking hands with…
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
DuoPlugin
DuoPlugin is a unique Minecraft plugin designed to link players' lives together, creating a cooperative "Duo" experience. When you are linked with another player, your survival depends on each other.
🔥 Features
- Shared Health: Any damage you take is instantly dealt to your partner. If you heal, they heal as well.
- Shared Hunger: Hunger saturation and exhaustion are mirrored. If you can't sprint, neither can your duo, and vice versa.
- Shared Effects: Drink or splash a potion, and your partner gets the buff (or debuff) too.
- Custom Death Messages: Unique messages when partners die together (e.g., "PlayerA and PlayerB died to Lava!").
- Request System: Safe and easy linking via
/duo <player>with accept/deny buttons. - Admin Controls:
- Locking: Prevent players from changing partners.
- Pausing: Temporarily stop the sharing effects without unlinking.
- Forcing: Admins can force-link specific players or randomly pair everyone online. (this plugin was originally made for an event)
🛠️ How it Works
- Linking: Send a request to a friend using
/duo <player>. They can click[ACCEPT]or type/duoaccept. - Gameplay: Once linked, you share:
- Damage: Taking damage hurts both of you.
- Healing: Regaining health heals both of you.
- Food: Eating food restores hunger for both.
- Potions: Splash or drinkable potion effects are applied to both.
- Unlinking: Use
/duounlinkto break the bond (unless an admin has locked duos).
