Atma?

[Amarok]

For brewing with Cataclysm, Cosmos/Hell's Gaurdian/Ultimate.

Interesting, I've always gone the Hexa Strike route on Shinryu, never failed. Usually have about 1 min left on the brew when he's dead, so never looked at the Staff option. (thats with MM, AoA & RR since its duo with MNK/WAR that needs to find blue proc first).
