Man I love that the devs put external cores in my favorite activity Sigma sector. Seriously I love it so much that I had nothing to do in that activity.
Bitching aside thanks to external cores above 34% hp managed to get 3k hp more in Serena with only 2 nodes of hp in arche board. So now I have 36k hp with inversion buff as well, this was more of a buff to Serena than anything else.
