I cant not notice you are kinda in confusion......Its a she or a he.
I say..underess char and take a closer look :D
Also if you put light set why you need heavy p/m def? And y, Knight tree is the choice for iss. Somehow you need to get to that cooldown ap skill.
your right :D female toon
Why heavy tree? cause of HP, cant learn it without, just like on robe and pdef.
btw you also make a bad grammar :D
So which 1 you advice? 12% pdef or 15% hp, will be a box iss for rbs.
