Oh this is a nice set. I completely forgot about Nusku's sash. Put that rajas like Dasva proposed and you are set. You could also swap agasaya's and dusk+1 for tiercel and dusk nq and stay "cheap". Or you could use while you are after dusk+1.
Anyway, this set is probably only useful against fodder mobs/low level nms. Raider's head and hands provide a huge boost to acc that will be put to use against high tier nms. Mars alone can't counter that loss. Actually by using 4/5 af + homam feet + rapidus + mars i doubt we would have capped acc against the hardest of the nms. Well, i'm just conjecturing based on my nin using little acc equipment against Orthrus (only parse on "hard" nm that i do have lol) and having 67% hit rate. This means that my thf needs 60 acc over my nin to be capped. Although it would be close to that amount with all those items, it's really not there yet.
So yeah, if acc is not a issue, i think this set (with rajas) has the best dps a thf could get. Other combos that keep high haste while still using nusku's would be something to check out too.
edit: oh yeah. Dasva added something that i forgot to comment about too and it's very interesting.
Using atma of the omnipotent.
With this babe you could ditch af body for dw mirke and dusk for af hands. It sounds really cool i'll tell you that lol. Would need some mathing to check for good~, but i really like the innovation.
