These are all accuracy sets bar Valk body, and are only really useful on T6+ VW and lolLegion. Having a distinguished high accuracy set and low accuracy set is
For Nyzul, VW below T6, and other events not listed yet, I'd say:
Minimum acceptable:
This is basic, and Kaerin got it right for the most part. It's still a very good accuracy set, having slightly more than the common Armada set. You can easily use Phasmida Belt+Mars Ring/Tyrant's Ring in this set for even more accuracy.
Medium level:
The set Kaerin posted is fine as an accuracy set, but Phasmida>Ninurta any time you would be using this set. The goal with high accuracy sets are to gain so much accuracy in gear, that you don't have to use Sushi, but rather Pizza. The ultimate goal is to be able to use RCB in an accuracy set, giving it more att than even an Attack set. You'd probably need Bravura 95~99 to accomplish this on T6 VW and Legion, if it is even possible.
For a pre-T6 VW set:
Notes: Phorcys Mitts might be out of reach for some people, in which case Augmented Seiryu's Kote>Ogier's Gauntlets>Perle Mouffles. Avant's hands +2, and Rheic hands +2 and +3 are also very good options.
High level:
The set Kaerin posted looks about right.
Notes: In VW (and probably any event with Embrava), Mars Ring > Tyrant's ring. Xhit is extremely devalued and losing 4 STP for 8 Accuracy is only an upgrade. Obviously, Phorcys Mitts when Restraint is down and the 12 accuracy is not needed. Bullwhip belt is fine, Phos belt is basically just for getting the 75 HP back.
Not an edit, but should be said: No way in hell Huginn Gambieras will beat Ravager's Caligae +2 without some sort of amazing augment, which is at this time unknown.
