Cheat Engine

[WillKill]

Hello, I'm new to cheat engine and I'm trying to hack Arcuz 2,

There is 2 Goal I'm trying to do

1. There is a "Crafting" System where it have a % Chance to Fail, Crafting Lvl 1 Have 100% Chance, Lvl 2 90%, Lvl 3 75% and so on. They are known Values, but I'm not sure how to change them since they are static (Atleast to my knowledge). The Goal here is to Change all of them to 100%

2. The Game have a certain % to drop something from an enemy, which usually a Chest or a Stack of Gold, and in that Chest, another % determines what the item will be (potions, equipment, gems, etc). The Goal here is to Increase the Chest Drop Chance aswell certain items from the Chest

I'd like for someone to guide me on understanding the basic of Finding Percentages, Thanks in Advance

You'll have a much better time downloading and decompiling the swf (e.g. JPEXS). Look online for tutorials.
