*Toreador to Eponas for TP
*Keep atheling for WS. Cavaros is only a piddly 3% crit boost for crits and does NOTHING for the ones that dont. Thf is still in the hole for atk compared to mobs and other jobs. 20atk will have similar and often better returns on crit hits, and actually works on non-crit hits of evis as well putting it way over the top. Thats before you count the DA.
*Get an agasaya collar to replace PCC.
*Dont TA in Svelte. -8atk sucks. Get a crudelis. 5str/5agi. Loosing 2 agi (2 base damage), get 10.5 atk, 5str (1.25 base damage). In total, you will gain 10-11 atk in exchange for nothing 25% of the time and -1 base damage the other 75% of the time. Complete win.
*AF+1 hands from limbus for TA
*Lithe boots for Evis over denali. 6dex(3acc) beats 3str and 5 acc. Dex is point for point the same as Str for evis, except dex cant cap. So 6 dex is 2x more powerful than 3 str and worth the loss of 2 acc and 1-2 atk. Plus, it simplifies stacked vs unstacked sets a bit. If possible, get Heca+1 feet and augment them. Mine are currently 9str, 4dex, 5atk. You can get up to 10 str.
*Ambusher's hose for TA. Agi+10 pants. No shocker there.
*Cuchulain's belt for both SA and Evis. As others have said, its good. 6 dex is great and 10 atk is superb. Thf always needs more atk.
*general upgrade: +2 Empy gear, better +stat ear/rings, all that good stuff that is rather obvious.
These changes should set you up rather nicely.
