[Pre-BB] MapleStory Formula Compilation

Simplifying the accuracy hitrate equation:

100% Hit Accuracy = (55.2 + 2.15 * (Level Difference)) * Avoid / 15
Chance to Hit = 2 * (Accuracy - (100% Hit Accuracy / 2)) / 100% Hit Accuracy


2 * (Accuracy - (((55.2 + 2.15 * (Level Difference)) * Avoid / 15) / 2)) / ((55.2 + 2.15 * (Level Difference)) * Avoid / 15)

2 * (Accuracy - (((55.2 + 2.15 * (Level Difference)) * Avoid / 30))) / ((55.2 + 2.15 * (Level Difference)) * Avoid / 15)

30 * (Accuracy - (((55.2 + 2.15 * (Level Difference)) * Avoid / 30))) / ((55.2 + 2.15 * (Level Difference)) * Avoid)

(30 * Accuracy - ((55.2 + 2.15 * (Level Difference)) * Avoid)) / ((55.2 + 2.15 * (Level Difference)) * Avoid)

30 * Accuracy / ((55.2 + 2.15 * (Level Difference)) * Avoid) - ((55.2 + 2.15 * (Level Difference)) * Avoid) / ((55.2 + 2.15 * (Level Difference)) * Avoid)

30 * Accuracy / ((55.2 + 2.15 * (Level Difference)) * Avoid) - 1

No level difference: (level difference = 0)
acc /(1.84 * avoid) - 1


With level difference:
acc/((1.84 + 0.07 * lvldif) * avoid) - 1

If what you get is over or equal 1, then you hit the monster 100%.
