МОД: Клинок Армагеддона / Armageddon's Blade

So, through trial and error. Or, in simpler terms: "by trying things out."
I managed to achieve what I wanted. The added skills that weren't originally part of the faction will now display information about them when you hover over them. However, I had to sacrifice the highlighting of dependencies (which skills are required to learn). But, as my signature says: just look at the arrows =)
