Which is impossible if you have the Zariche (unless you self buff or use CH... in which case.. you'd have to be ******ed to waste money on them). This is why people pay an arm and a leg for them.
And before you say it isn't worth it... consider this. My friend, a BH, went from 73@30% to 76@10% in a week when she got the Zariche to herself. Lucky for her too, because we had won Dusk vs the entire server, so the catas where completely empty. And what she lost in buff scrolls... she made up for in seal stones and drops.
