So I'm trying to figure this out for someone, and here's what I came up with.
10 base
04 insight green steel weapon
05 protection green steel helm
16 epic cavalry plate (mdb 3)
01 alchemical ritual (armor)
03 16 dexterity
02 fighter armor mastery rank 2 (requires 20 dex)
02 stalwart defender 3 mdb (requires 24 dex)
08 shield light and darkness
01 alchemical ritual (shield)
01 superior stability (on shield)
05 combat expertise
03 stalwart defender 3
02 stalwart defender ToD set
01 dodge feat
02 tharaak bracelet
66 (68 with 24 dex) unbuffed
14 base dex, +6 item +2 tome +2 ship buff (not too bad, but more than I'd like them to put into dex).
Other than the obnoxious dex required did I get everything correct for a sustainable armor class? Am I missing anything? Please do not count buffs, unless they are self buffs.
