The cloaks lvl second element could accept all six types.
The mounts (horse, lion, ant) could have the skill to run the same way as the mounts of the classes awaken.
The hair accessories could accept pendants dex, str, critical, etc..
Since you can not even equate the equipment purchased in L2Store, there is no reason to buy these items. The player purchases, but when a pvp or any violent scenario can not use because the equipment acquired in-game without ncoins is much better.
the itens obtained ingame arent better, but the improvements you do to them is. The reason for anybody buy any of these cosmetics itens is "customization"; since even from startings levels everybody just looks the same (everyone uses PoA's itens = same gear/weapon/appearance), sometimes only these stuffs will make your character "unique", in certain way. Others, as me, will buy if the item was cool enough or even 'cause a nostalgic feeling (aka princess ant mount).
I really liked the customization items. Especially the Cloak of halloween, Queen Ant mount, and the Warrior Helmet. But stay cool STR -3 expense of a pendant for example. Having the Queen Ant as costs mount to be much slower. I did not want it to be higher, but at least they stay the same.
Sure, it's just an idea.
Use hair acessory stone appearence changes a hat that I already have for the Warrior helmet for example? I'm asking because I have not tested.
