20% Anniversary Scrolls and Protector Shields.

The text is not ambiguous at all (though it's kinda badly written), from what's written it clearly works on other scrolls too.

Also, nexon's text on cubes wasn't ambiguous either, just downright wrong, which could be the case here too.

i meant spadow, and the only reason i am not 100% sure on how these darned things work, is due to how nexon is great at screwing up the simplest things, "rare" items, for example as you said.
