I think x-3 is a better option.. Novas are just to expensive ip wise.. I also used nova but switched to shotgun couse i couldnt keep my nanoskills maxed with nova.. depends on ql of gun of course but think x-3 is a good option.. You know we got a conceal buff too
And btw the area calm is a ql 126 nano... But single ones work great to, I can calm max level mission without area calm...
Good luck!!
