What is this CS item?

just protect items from being destrouyed if you use enhancement scrolls, and if your item have more than 8 stars, it wont work.

so people that can spend 10k dollars/week on maple, will have all their items with 8 stars, and nexon say, nx wont affect your gameplay..

The CS item is only worth using on your weapon anyways, since it's essentially a free +24atk. Dunno why you would waste money on enhancing your other stuff to +8 when you'll only get +stats.
