Well I may as well say it now.
The ability I got was the very first one he mentioned - the restoring broken abilities. I found it too perfect since when I checked Zara, and asked for his scummiest active ability, he first named the one I did not find, and then he immediately named the one I did find.
I thought I could play the game with TKOTS, see if I can get any other active ability. You saw what happened... He couldn't say another one on the spot, and then when he eventually did claim another active, I didn't understand it at all and he did not explain it when I told him I didn't understand. It was very vague and honestly not like one I've ever seen before in a game.
