A note about Mk.26 gear- This is 220 rated gear. It is one step below 220 dropped gear but one step above 220 commendation vendor gear. It provides a great alternative while waiting for drops from Ops. They are especially good when considering the non-legacy slots such as implants, relics, and ears. Mk.26 gear requires 3 Strategic Resource Matrix and 8 or 10 exotic Isotope stabilizers. If you've been doing conquest lately you've gotten the matrix everytime for completing your personal goal. Otherwise the go for $250,000+ each on GTN. If you've been doing Ops and FPs youve got the blue crystals to buy exotic isotopes at 25 a pop from the Odessan vendor.
I'll craft any of this for free if you supply the purple and blue materials.
