High MP Bishop

It's really just the same as above, but with HP rather than MP, 3 Set Empress, I use gloves, shoes, and overall on my bishop, but any combination would work, minus those including the hat, cZak scrolled for HP, Rex Earrings, I also have 60HP nebulites on everything, the highest C Rank HP Nebulite. Luckily, besides nebulites and potentials, most stuff that raises MP also raises HP, so just doing what you were planning on doing should be sufficient.

Dedicate as much of your resources as possible to hitting 42.5k MP, with perhaps a bit extra for a heal or two, then the rest of your gear should be focused on raising your HP. I don't remember how much Empress and her friends do, but I believe you could tank two hits with 15kish HP, but the more HP the better, else you face what priests did training at Himes with a DK.

Once we get the character card system, you could also get a few extra % HP from having a Spearman/DK/DrK card. (If you were wondering, the % MP counterpart is the F/P mage). Though the max you'd gain is 5% with a 200 DrK/F/P

I'm sure others could offer you more current advice, though, I rarely ever use my bishop for Empress anymore.

Hmm, I do remember DR bypassing MG, but I'm not sure if they changed it recently, probably not though, worth testing.
