Oh, hi Flinchy! One question... how do you actually get psionic ability? I'm a little lost on that part...
Oh, I see, sorry!
You can acquire Psionic skills by using the chair in the east wing of your Safe House. There are many other upgrades there as well, that you can acquire by exchanging EXP.
The southern purple section of the upgrade area pertains to Psionic abilities, so you can find several there. Hope this helps!
