On the character attributes page is a section for abilities (different from talents). I've earned the abilites Axii sign hex, cover, conjuror and assassin. Each of those gives a certain bonus, which is nice, but I have no idea how I unlocked most of those abilities.
I got the Axii sign hex when I first used Axii in a conversation, but I've no clue how I unlocked the rest of them. Are they given to you on certain events, or do you have to do something special to get them?
