Is there any armor combination

do I need to have a special combination of armor or can I just put on what I think is the best

 

until you get to endgame (lvl 95+) you'll be fine just wearing whatever armor you have that's near your level

 

It depends
There are things that are good, but like the person above said, u don’t need to worry about it til 90+ or smth
U can get specific builds whenever u want, but it’s not advised for earlier lvls cause u outgrow them so fast so not very worth
Tho if u want a good Set for the whole game use morph, it scales very well for ur lvl
Just use as many pieces as u can for ur lvl and fill the rest with random pieces

 

there are certain combinations of armor and/or accessories referred to as sets in-game, but as Ninja_VK said above, the morph set works very well even in the endgame

also you won’t have to make specific builds until like level 95+, just use whatever items you think works best for you
