This is a restricted weapon in that you are only allowed to buy up to 65 from the shop directly. It'll cost you 2,800 Ferrite, 1,900 Bioptics, and 74 Crystal to buy one. It does allow for bulk purchases and you can buy 5 for 260 Crystal.
Now with that hefty price tag in resources the question is simply, is it worth it? It deals out 77 straight damage, has a speed of 102, and the weapon ability of 2X Damage at 10%. These things are some hard hitting, fast firing lasers plain and simple. They are perfect with the Fext build especially seeing as the right equipment installation can have you running 3X Damage at 94%. Add in the fabled X9 hits those things are capable of and you have pretty much vaporized your opponent.
As this is a higher level weapon you can be sure that higher level players will be changing them out in between laser build bonus mechas to see what all they can do. Best advice is if you face someone with an arsenal of these invest in good strong niode shields. It may not save you completely but it may let you last a round or two longer. These are nasty weapons!
