Duplication Glitches:
(In the text below, "donkey" refers to ChesteredHorse in the BukkitAPI, including mules, llamas, etc.)

Many anarchy servers, e.g. 2B2T.ORG and 2B2T.XIN, have intentional/unintentional item duplication exploits.

1. The 2B2T.ORG server has had multiple duplication glitches. The plugin implements the most classic one—"donkey duping"—where a specific method allows duplicating a donkey including its chest with items. Meanwhile, the 2B2T.XIN server adopts a simpler and more direct approach: players with permission who kill a donkey receive double the drops.
   
   
2. Command-based duplication was used by the closed 2B2T.ICU server, where entering a command duplicates the held item by a specified multiplier. The multiplier is usually 2 times.
   
   
3. Item Frame duplication was a method once used by a famous Chinese server but I forgot its name, where rotating an item inside a frame has a possibility to yield an extra copy of the item.
   
   
4. Mine-Place duplication, e.g., x+1 (where x is set in config.yml), where mining a shulker box x+1 times yields one extra shulker box.
   
   
5. Chicken dupe. The first method, from the bbttcore plugin by developer zszf, allows duplication simply by clicking. The second method, currently used on 2B2T.XIN that allows right click the chicken and it will spawn shulker boxes, triggers at specific times (currently fixed minute intervals, default: 0, 15, 30, 45)**.
   

Miscellaneous:

1. Player Statistics: Allows querying or tracking online players' kill counts (can include crystal kills), deaths, online time and join/quit counts. Data is stored using the server's native PDC. If you want to use MySQL or other things to store, please discord me. I don't want to implement them without anybody's using.
   
   
2. Suicide Command: Same as EssentialsX's /suicide. Aliases: /kill, /514, /suicide, /自杀. Admins will directly use /minecraft:kill to enable selector usage.
   

Limitations:

1. End Crystal speed limit. The "speed" here refers to placement speed, measured in milliseconds.
   
   
2. Speed limit for entities passing through End Gateways (e.g., minecarts) and for TNT entities. The cooldown is measured in milliseconds.
