Heavy Strike low accuracy problem

[Kwate]

Eyeballing it, I've had some pretty decent luck with:

ammo: Mavi tathlum (until i get mantis's eye +10 Acc)
head: Aias bonnet
neck: PCC
earrings: stay with tp
body: magus jubbah +1 (unless i read another piece outperforms) (also debating if i should just keep AF3 body piece on)
hands: Palla's bracelets
rings: spiral, rajas
back: cuchulains
waist: warwolf
legs: AF3+2
feet: Homam

don't really use food much tbh.
swords: Almace and DA (thought about offhanding Dex for Acc, but not sure a single spell or losing DoT on aftermath is worth offhand change)

I do get those annoying, gut wrenching misses, but i seem to hit pretty often ranging 800~1400, Eff 1800~2800 (i can't bring myself to gamble CA, I save those for my Quad casts)

Made some revisions:

ammo: Mavi tathlum
head: Aias bonnet
neck: Chivalrous Chain
earrings: stay with tp
body: Alcide's Harness +1
hands: Palla's bracelets
rings: spiral, rajas
back: cuchulains
waist: Anguinus Belt
legs: AF3+2
feet: Homam

Did some testing last night with gear set changes on La Theine T2 VNM's while attempting to get T3, landed 17/18 didn't jot down exact damage (mainly keeping track of hits vs. misses), had RR/GH/SS, good to see it landing pretty often. I'll play with it more vs. VT~IT and boss types.

Edit: no food
