Remember, there's no hard evidence that 2 dex = 1 acc. If you re-read the SE interview frequently posted, you'll notice they do say 2 vit = 1 def and 2 str = 1 atk, but not 2 dex = 1 acc or 2 agi = 1 eva. They state that it's better to directly raise acc than via dex, so it's not a 1-to-1 relationship... and if it were 2-to-1 like vit/str, they would've just said that. So likely, it takes at -least- 3 dex to get a point of acc by your own stats... possibly more.
So yes, the bracelets are quite awesome... I like to swap them and a swordbelt+1 in while sneak-attacking, since it's a guaranteed critical hit, I'm adding 7 STR and 12 attack to the cause. Owch X) I don't leave them on though, -4 agi? Yikes...
Onward, some other equipment thoughts up to 70... A bit of this is easily attainable/cheap, some of it is kind of expensive, and a lot of it is expensive or difficult to obtain. Still, it's a sample of items you should keep an eye our for, in my opinion...
Waist:
Level 43 Swordbelt/Swordbelt+1, great DD until Life Belt
Level 58 Master Belt, a good option if you don't need as much acc as life belt, but swordbelt's 0 acc is too little.
Back:
Level 55 Federation Army Mantle, a great tank item, requires rank 6
Level 55 Royal Army Mantle, DD, requires rank 6
Level 60 Behemoth Mantle, tank
Body:
Level 60 Byrnie, awesome armor, huge boost to damage and doesn't gimp you as a tank like haubergeon does. You can even put Defender on and still hit hard.
Level 69 Hauberk, DD, just trade in your haubergeon
Earring:
Level 1 Cassie's Earring, tank or DD, I hope you're rich!
Level 30 Pilferer's Earring, /thf DD sub. Who'd argue with an extra 2 dex?
Level 30 Genin Earring, /nin tank sub. An extra +1 agi over a drone earring.
Level 58 Assault Earring, pure DD.
Level 70 Fenrir's Earring, DD, good luck getting this or...
Level 70 Pixie Earring, DD, that.
