[Pre-BB] MapleStory Formula Compilation

MAX = ((Magic²/1000 + Magic)/30 + INT/200) * Spell Attack
MIN = ((Magic²/1000 + Magic * Mastery * 0.9)/30 + INT/200) * Spell Attack

what does it mean by magic?
Isn't it the same as INT?
INT provides Magic Attack.

Also, whats the mini 2 on the left? Magic² = Magic x Magic ?

Magic is the Magic Attack value shown in your stat screen. INT does provide Magic Attack but they're not the same. Magic Attack includes the number on your wand among other things.

Yes, a superscript 2 conventionally denotes squaring.

1) what does standardPDD means?

It's a value that the game decides is the "standard" amount of defense you should have. It comes into play with the damage formula.

2) could someone rephrase this sentence below, because it doesn't make sense to me.
Note: Formulas for skills with a damage percentage list the skill's base damage, i.e. before the damage percentage is applied.

This means, that, for example for the Lucky Seven formula:

Lucky Seven/Triple Throw (credit to HS.net / LazyBui for recent verification):
MAX = (LUK * 5.0) * Weapon Attack / 100
MIN = (LUK * 2.5) * Weapon Attack / 100

Maxed L7 is 150% damage, so you have to multiply this result by 1.5 to get the real damage. The formula gives what damage you get before you multiply by what the skill says.

3) For buffs like "Sharp Eyes", which category should it go in? Is it under modifiers?

It would go under modifiers. However, Sharp Eyes does exactly what it says it does, so it needs no formula.

In this case, Sharp Eyes is actually mentioned under "Order of Operations" because that's where it explains how damage is applied.
