The grail is misleading as it advertised as "an in-game item that allows you to colour your items in gold and sell them for more". While technically accurate, I don't think I'm too off in suggesting it should have specified "armor" instead of implying any item.

"an in-game item that allows you to colour your items in gold and sell them for more"
"an in-game item that allows you to colour your armor in gold and sell them for more"

Why not just say the latter when advertising it?
