[Pre-BB] MapleStory Formula Compilation

Yeah, I hadn't used my BM much in the past 5 months, but I realized yesterday that I was doing well over 3k damage with PKB, even though my max damage is in the 2600s (lol half-stripped). The PKB formula can't be right.

I'm fairly sure this is what it is:

(DEX * 3.4 [* 0.1 * 0.9] + STR) * Weapon Attack / 150

Updated with that and sin punching. Any confirmation on SSKick/Blank/Grenade? Fiel still says it's just normal damage without bullets, but it doesn't seem so...
