- Instant Database Backup: The moment a duel is accepted, the player's Survival inventory is saved to an SQLite database within milliseconds before being cleared.
- Anti-CombatLog Protection: If a player tries to Alt+F4 or disconnects mid-duel, the plugin clears their temp kit, declares them the loser, and automatically restores their original inventory when they rejoin. Zero lost items, zero dupes!
- Strict Command Blocking: Players cannot run commands from other plugins during a duel, preventing teleportation, healing, or economy exploits.
- WorldEdit-Style Selection: Use /simpleduels wand to mark arena points, define spawns, and save it instantly via commands.
- Automatic Arena Cloning: Multiple players want to use the "Desert" arena simultaneously? SimpleDuels clones the arena 20 blocks away for the new match and deletes it when finished—saving world space and memory.
- Up-To-Date Kits Included: AnchorPvP, CrystalPvP, AxePvP, OP Netherite, and the brand-new MacePvP (featuring Elytras, Wind Charges, and Maces).
- Custom Kit Layouts: Competitive players can run /kit editinventory <category> to customize where items land in their inventory (hotbar, offhand, armor slots). SimpleDuels saves these preferences for all future duels.
- 100% Configurable & Translatable: Custom GUI menus, titles, and messages via lang.yml.
- 5-Second Countdown: Players are frozen during a countdown while being allowed to organize their inventory before combat starts.
