Southperry's damage calculator - Magic damage.

In Maplestory, open up your stats window. Click the little arrow at the bottom of the stats window to extend the stats window to the right. Your magic attack value is located in the right pane (should be neatly labeled). Input that magic attack value with the INT value in the left pane.

This should be the correct inputs:

 The problem is

It's called "Magic" in-game, thus the confusion. Do I input Int values and then another values that's already containing the Int value in itself? Makes no sense. So I assumed it to be the "Matk from equips/buffs", which implies a total Magic damage (shown in-game) when added with Int itself.

Although it makes sense that the value that's above "Magic Defense" should be "Magic Attack", not "Magic".
