用 YEP_ExtraEnemyDrops 这个插件。
就是不知道里面的 批量设置怎么用
* <Enemy Drops>
* Item x: y%
* Weapon x: y%
* Armor x: y%
* </Enemy Drops> 批量设置掉落物品及概率
* Alternatively, using the above notetag format will allow you to group a
* large number of enemy drops together. Replace x with the item, weapon, or
* armor ID to give the item a drop rate of y%.
