While shadows are up, I'd drop the torque and herc ring. Not sure what I'd use, but probably chiv chain or something similar to that; more damage dealing gear.
For spell casting, I have three different sets actually: a haste/FC set, an enmity set, and a shield set.
Shield set is really only used for utsusemi: ichi and any other spell that has a chance to be interrupted. I could probably change this now with all the FC gear/atma.
Enmity set is for anything that I use to generate enmity: flash, provoke, etc.
I macro in my haste/FC set for almost every spell I cast, but I stay in it for utsusemi: ni.
I've completely stopped gearing for HP due to abyssea. Cure cheats are now as easy as clicking off the HP buff. I also tend to gear up in more MDB and MDT gear even when shadows are up if I'm tanking anything strong. I find too many NMs now spam a ridiculous amount of -ga spells of varying elements, this leads me to gearing for magic damage. Anything that has a single element (Drauga, Orthrus), I've got resist sets.
Don't know how but MDT/MDB set totally slipped my mind, how's this: http://www.ffxiah.com/item-sets/196390
? (Adaman legs ANNM -2% MDT aug, swap in Jeweled collar instead of Invidia when appropriate.)
Wouldn't it be best to just macro this stuff in for spellcasts/WS assuming that is possible? Obviously on some fights where the mob may have instant cast or extremely quick WS that may be impractical/impossible.
I also made changes to Shadows Up per your advice, I also realized Creed Earring was doing nothing for me in that scenario as well, so I made some revisions: http://www.ffxiah.com/item-sets/196299
I can't really find anything better for neck than Chiv chain that isn't a few million gil, so I went with that for neck. Edited, Jan 19th 2011 10:36am by RamseySylph
