Making Rukia powerful

Brutalix

Hi I just got Rukia at lvl 50 and from what I read she is quite useful in PVE with her fury attribute enhancer to the team, but could anyone advise me how should I go about making her more powerful in her attacks with Refining and Spirit Stones?

Are my refines and Spirit Stones in order and should my priorities to increase the lvl of my spirit stones goes to Wisdom, then Agility?
And till what lvl then they should be in the average power range to survive in the 2nd Stage of Trial Tower - Nothingness and to do well in the PVE events like ES and Ryoka attacks?

My gear refines and Spirit Stones:-
- Weapon
Wisdom, Hit Rtae
Lvl6 Agility, Lvl6 Wisdom, Lvl4 Hit, Lvl3 Dodge, Lvl5 Break Def, Fury stone +10%

- Headband
Stamina, Wisdom
Lvl3 Agility, Lvl3 Wisdom, Lvl2 Stamina, Lvl2 Hit, Lvl3 Dodge, Lvl1 Block

- Armor
Wisdom, Agility
Lvl2 Agility, Lvl3 Wisdom, Lvl2 Stamina, Lvl2 Hit, Lvl3 Dodge, Lvl1 Block

- Cloak
Agility, Wisdom
Lvl2 Agility, Lvl3 Wisdom, Lvl1 Stamina, Lvl2 Hit, Lvl1 Dodge, Lvl1 Block

- Boots
Critical, Agility
Lvl2 Agility, Lvl2 Wisdom, Lvl1 Stamina, Lvl2 Hit, Lvl1 Dodge

- Belt
Agility, Wisdom
Lvl2 Agility, Lvl2 Wisdom, Lvl1 Stamina, Lvl2 Hit, Lvl1 Dodge

Here is the stones i use: 6 agi, 6 wis, 6 break def, 6 crit, 6 counter, 3 hit, 3 stamina.  dodge really doesnt work out that well so i find its better to put counter stones and tank it. the stamina stones also help with tanking.

main attribute for Rukia is: Wisdom, Critical, Agility (if you need her to run 1st for t1, otherwise she should always go last).
secondary attribute (so she can tank longer - in PVP only): Stamina, Counter
you can mix the following for the remaining sockets: Break Def, Hit Rate (her purpose is to provide fury, either she get blocked or dodged, the job still gets done)

and doing trial tower, you need to have a stronger overall lineup, not just a strong Rukia.
