How does Maple Warrior work?

Lol? It only affects base stats. To explain your above post, read below. The skill bonus appears in the same location as gear AP bonuses, which may be why you're confused.

MW works by effectively "adding" a percentage of base stats to your overall AP stat, which shows up in the same category as additional AP from gear. For example, if I have 999 base INT and use MW30, I'll add 149 INT (again, sadly, it always rounds down). So, my INT stat after using MW30 would appear as "1148 (999+149)." If I had, say, 160 INT from equips, with my pre-MW30 INT reading "1159 (999+160)", the new stat would read "1308 (999+309)" upon using MW30.

Hopefully that makes sense. And of course, the skill affects all APs, all equally (so if I had 999 base INT and 23 base LUK, with no boosts from gear, my stats, upon using MW30, would read "1148 (999+149)" INT and "26 (23+3)" LUK).

Thank you this helps alot This is exactly what I needed to know.

I guess THIS is another reason why "stat"-less classes tower over their normal brethren?
