Item drop rate
The formula is calculated if the soul from previous calculation isn't acquired. Julius Mode skip this.
If Rare Ring isn't equipped:
Numerator of the chance of a common drop = 3/4
Numerator of the chance of a rare drop = 1/4
If Rare Ring is equipped:
Numerator of the chance of a common drop = 5/8
Numerator of the chance of a rare drop = 3/8
If enemy has no item on the selected (either common or rare) slot:
No item dropped
Item rarity
Rarity = drop rarity (depends on the slot)
Rarity = (Rarity x4) + 16 - (LCK/16)
If Rarity is less than 16, set Rarity = 16
If Rare Ring isn't equipped
Numerator of the chance = 4/Rarity
If Rare Ring is equipped
Numerator of the chance = 8/rarity

可以参考下
我以前查过晓月的掉宝率时 发现这个运算非常之鸡贼 好像还有不管你lck多高都保底的"不掉宝率" 切
对于这种看不惯的果断开老金lck999 = =~

其实都差不多，就算吃增加幸运的药，稀有道具掉落依旧很难，基本都是第一遍速通，从二周目时开始细刷装备

幸运高了，游戏没意思。
你以为是宝随便掉？
错了，经常秒人才无聊。

当然是同时装备两个稀有戒指。幸运高确实是提高掉落概率，但掉落什么都有可能，大小爱心、100以下的钱、普通物品或者珍稀物品，只有稀有戒指是确实提高珍稀物品爆率的。所有双稀有戒指加伪孝子三件套才是王道
