In short, there was something I made and thought wasn't working, but it turns out it does (I noticed it by chance, as I simply forgot to delete it, and when testing a completely different part of the mod, this thing popped up). Now I'll rework the skill tree again because it's possible that most factions will have two specializations (one from the path of magic, the other from the path of strength), or at least I'll add one strong racial perk to the list, obtaining which will make it impossible to get a specialization. I won't reveal the details until the release – suffer now:D :D :D :D :D :D :D :D :D
SRD, can you upload your work as a file? I'd like to check it out.
