Last I checked this was 550-600k on Odin. Probably worth it though if it's a BCNM60 drop. I should probably be saving now, I have staves but during fights when I cast I use Crimson Blade, so I'll still need a shield.
IMO this is the best shield a Red mage can buy from the Auction House. The Astral Aspis is better than this one because it also adds intelligence.
Late game, unless you have excalibur, red mages use the elemental staves so having a shield isn't even really necessary. I bought this shield for my rdm at 58, but then sold it when I hit 66 for the Enfeebling torque since I couldn't usually take advantage of the extra 30 mp unless it was right after convert (With a staff - in my case dark staff - equipped you can't put anything in your sub weapon spot so I'd never med back the 30 mp).
Eh id much rather uses staves, the only real time you would be using a sheild is solo with BLM sub... which I would rather have a darksteel buckler for the attack, or balance buckler for accuracy. Most of the time i solo as RDM/NIN or RDM/BST and with /BST i use Light Staff mostly.
BCNM also drops Vassago's Scythe and other valuable items. P.S.= The BCNM are 6 NM Quadavs that all use there two hour during the fight. Only attempt with a skilled party!
