[Phasma]

My fox is currently have a 36/31 4141 fox with all bonus points into DA.
After reading a few guides/threads; I noticed most people do not recommend a 4141 build for a DA fox.

Should the fox be remade as 1144/other or would the extra points from Ap/Ac be more beneficial then charm?
If my fox is in need of remaking, is there any way to make her useful with the current build?
Skills- Mastered stone strike/mastered sixth sense/level 3 shuriken mastery.

Thinking about equipment as well, not sure whether to go DA/Lk for weapon+headgear and WT/HP for shield; or skip compounding to wait for higher level items. Currently wearing- Ult knife(3)/Ult shield(2)/Looking to get a Ult headgear.

Also, although stone strike is a great skill; is it essential to master?
Fsk seems interesting as well; worth getting despite high tm cost?

If it helps, I have 1-2million in total value to work with.
