[Pre-BB] MapleStory Formula Compilation

That is true.

Updating thread.

also, just fyi:

weapon damage:
(Base Damage*Elemental Charge * Elemental (dis)Advantage - Defense Reduction) * (Attack Percent + Critical Bonus) * Effect Multiplier

Those are included in Effect Multiplier (which is everything in the 'Effect Multiplier' spoiler tag except actual attack skills). As for whether they come before the defense reduction and everything else, I'd doubt it. As far as I know, all multipliers come after defense, and everything other than the actual attack skill's damage comes after critical as well.
