[Pre-BB] MapleStory Formula Compilation

Combo Attack
Combo Multiplier = (115% + Advanced Combo % + 5% * number of orbs)

Combo, if you have Max Combo Attack, would be 120% + AC percent + (5% * orbs 2-5) + (4% * orbs 6 - 10)

The 120% would be the 1st orb wih just max Combo Attack and it grows with the AC percent
-

Finishers = Skill Description % * Combo Multiplier * number of orbs / 2

This formula only works with max combo attack and a maxed finisher and stop working with AC orbs.

From what I've seen This post is right

Combo Effect % * Finsiher % * Orbs Multiplier

The orb multipliers are:

1 orb = 100%
2 orbs = 120%
3 orbs = 154%
4 orbs = 200%
5 - 10 orbs = 250%
