[Pre-BB] MapleStory Formula Compilation

1-correction only appears to occur for the Level Multiplier, but not Effect Multipliers.

So, [(Base Damage * Level Multiplier) ~1-correction] * Effect Multiplier * Element, etc, etc.

Iron Arrow's .9^x reduction, Arrow Bomb's 5/13ths reduction, Slash Blasts .33^x reduction.

I think it's more like 1/99 999-correction only appears to damage calculations where the damage is independent of other attacks, else damage would be corrected to 1 and then skill multipliers go and make e.g. 2 damage (for maxed powerstrike).

Iron Arrow, Arrow Bomb and Slash Blast all miss when they hit a monster if the previous damage was so low that diving/multiplying with their multiplier would create a number lower than 1. That would also explain piercing blow going over 99 999.
