Covenants Lab Specialization

Need Help here:
If I add Greater Feature (a Forge) and choose the following: +3 Terram, +2 Aesthetics and I add a Greater Focus: -2 General Quality +4 Terram, will the -2 from G.Q. add to my terram and only give me: +5 Terram or will I have +7 Terram?

-2+7=5

It's the downside of things that negatively impact GQ.

But the focus is Terram, should the -2 for G.Q really reduce the specialized Terram ?

Yes.

Everyone is right, the -2 will take away from your Terram. But what do you care? Greater Feature stacks..........
