I can't buy one. Today I spent literally hours shopping for this motherfucker. I have seen Tesla Gun, Flame Thrower, Rifled Cannon, Grenade Launcher, Acid Gun ... You name it, I have seen it multiple times for sale. But no Charged Accelerator Gun. Is there some level requirement for certain schematics to show up? I am Level 35 btw. Or is it maybe the vendor? I tried Tarant (all merchants who sell schematics) and Ashbury (the gun shop).
