PC my ES Vaal regalia/ and some help please!

I recently crafted this ES armor, and I dunnow hich craft mods I should put on it, also how much would it be worth?




I was thinking for the last prefix craft % energy shield with life, and for the last 2 suffix's either quality with dex, or quality with intel, and gain 60 es for each rare or unique monster near?

any and all input would be greatful!

600 es chest piece goes for 50 chaos orbs but since you have open space left you can craft some elemental resistances and sell for 3 exalts +
