It shows max AC is 90, while somewhere it was said that AC could be higher and 90 isn't cap, so you could have 120 AC or even 140 AC for HtH, while it shows only 90. The same with ToHit calculations, max AC of target can be set to 90 only.
Also in perks descriptions, "enchantment"? You mean enhancement but mistyped?
Edit: also, please add flamer to ToHit calculations ;p
Edit#2: also throwing weapons like molotovs and knives.
