Luck manipulation

I did disassembly analysis, and I made item prediction Lua Script to optimize collection Bolts and Weapon energy. In this game, item drop pattern is divided into 6 types. But, first type's all of probability is zero. So I call this "Type 0" as a matter of convenience. Here is item drop table.
TypeLife smallLife bigWeapon smallWeapon bigBolt smallBolt big1up
000000000000000
120182018000001
230300808303001
308083030303001
418101810383003
510081008504002
These values are stored in 0xC0BA8D ~ 0xC0BABC. The numerical value which broke these values by 0x100 becomes actual probability. For example, big Bolt in type 4:
0x30 / 0x100 = 18.75%
Therefore, it comes out by the probability of 18.75%. Here is the script source code.
