Combat Persistence 🛡️

Combat Persistence is a professional-grade, 100% server-side Fabric mod for competitive Minecraft servers. It kills combat logging by spawning a vulnerable NPC whenever a player disconnects mid-fight — so closing the game is never an escape. It also ships a hardened, built-in authentication system to lock down offline-mode and cracked servers.

No client install required. Your players just connect and play.

⚔️ Combat Logging Protection

Smart Combat Tagging — Players are tagged only on genuine PvP damage. Configurable duration with live action-bar feedback.
Persistent NPCs — Disconnecting while tagged spawns a Mannequin NPC at your exact location that mirrors your skin, armor, and held items.
Survives Anything — NPCs are backed by NBT data, so they persist through chunk unloads and full server restarts.
Reliable Offline Deaths — If your NPC is slain while you’re away, you rejoin straight to the death screen. No ghost items, no survival glitches.
Advanced Dupe Protection — Clears both the inventory and the cursor stack the instant you disconnect, closing the duplication exploits that plague other combat-log mods.
Command Blocking — Stop players escaping a fight with /tp, /home, /spawn, /warp, /back, and any custom commands you add.

🔐 Built-in Secure Authentication

BCrypt password hashing — Passwords are never stored in plaintext.
Inventory & coordinate hiding — Until a player logs in, their inventory and location are concealed, so nobody joining under their name (a real risk in offline mode) can peek at their items or position.
Brute-force lockout — Accounts lock after too many failed /login attempts for a configurable cooldown.
Operator account reset — /authreset <player> lets staff wipe a forgotten/compromised account so the player can re-register.
Conservative IP auto-login — Optional and off by default (IP auto-login is weak behind shared NAT / BungeeCord / Velocity proxies). Enable only on trusted direct-connect servers.
Safe limbo — Unauthenticated players are held in a lobby with hidden coordinates to prevent world-leaking.

🪓 Arena / SMP Extras

Ender chest toggle — Optionally disable ender chests server-wide (reliably blocked via mixin) so players can’t stash loot mid-fight on arena/SMP setups.

💎 Why Combat Persistence?

Built with an exploit-first mindset. We’ve manually patched duplication glitches (cursor stacks, inventory ghosting), offline-mode identity spoofing, and authentication bypasses that affect other similar mods. It uses ReentrantLock and background saving to stay thread-safe and lag-free under load.
