[Pre-BB] MapleStory Formula Compilation

So this means you take a monsters wdef and multiply it by one of those multipliers and then subtract it, or do you outright subtract the monster's wdef, because it seems kinda odd that max and mins would have different defense reduction multipliers

Yes, they do have different defense reduction multipliers.

Example. 10000~10000 damage range. 3000 DEF.

Max: 3000*.5 = 1500 reduction. 10000-1500 = 8500 damage.
Min: 3000*.6 = 1800 reduction. 10000-1800 = 8200 damage.

So your real damage range ends up as 8200~8500.

It's been tested with tight damage ranges. More defense spreads the min and max out.
