Hello, I don't understand what is the right meaning of those "common items" in gracia_pt#2, could somebody answer me with explanation about that, please? thx 4 an answer how to work with them or how to upgrade those items. tha a lot! have a nice day!

as far as i know, they are just like normal items, but with way lower crystal count, cheaper, non-enchantable, non-sa-ble, augmentable, so like a shadow equip but can be crystalized and never goes away.

and if i know well, common set won't give any set bonus

Common items are cheaper, usually easier to drop, you can't give them SA (weapons), their enchanting is possible but limited, armors don't give set bonuses, you can't augment them, can't store souls(Kamaels) and you get less crystals than normal items from shops.

Imo only Common weapons are worth

as others said..i agree.. you know what its better to buy common items than using shadow weapons when in D-B grade even in A grade weapons..

I don't think that you can buy D shadow any more... At least I couldn't at 20 lvl in Aria... I just bought top d 70 k common weapon

common items are NOT enchantable
crystal count once crystallized is around 10 times less than normal items
augment/sa are not possible too
but you can dual 2 common sword to get common dual
u can unseal common A items too
set don't work

on offie, the most common used are shield for mage and jewels, easy to drop and good mdef
some weapons too for 2nd weapon use like bow for tank or common dual/dual hand for vanguard transformation
