Chaos Scroll

does chaos scrolls only affect att?
like, if i scroll a zhelm with a chaos scroll, can it improve the luk on the zhelm?
will it improve only the luk (or dex or str etc..)
and how about m.att?

Chaos scrolls can effect all stats on an item. Weapon attack is most mentioned as its the most useful (Afterall, we dont have glove wep atk scrolls that add +5 atk and we dont have cape for atk scrolls at all).

That being said, yes it can increase the luk on a z-helm, though it'd be a big risk and can take away/break it instead and whatnot, not to mention that they're too expensive to mass scroll right now for the average mapler.
