MF Sorcy: Reccomendations

You should max cold mastery too.
Decrease you warmth to 10 (with the items, you'll get around 17)
and static field. Put just 1 point : with items you'll get around 8, witch is sufficient.

Edit:

Oh and btw, max your dex till you get 75% (depends on your CLVL and witch shield u use. I use Whitstan's Guard, coz it has a lot of block, and with 162dex at lvl 85 i hace 75%)

Put point on strg till you can wear your stuff (you can choose to increase till you can wear the higher requirement, or just to wear the first that give you +stg till you can wear everything)

all rest in life

none on energy
