you cant take support perks via drugs?
There's obviously a max somewhere a long the line, but it's only determined by how many sources of AC you can find, there is no cap in place.
If you want to make enemies, try to change something.
It needs fixing atm
Ok great So I can continue with my 150AC character without worrying that I will waste 3 perks? (by taking another AC perk after hitting 90)
What does Pack Rat do, exactly?
