There is a very well established process to get inducted, so established there is an in game object that spells out what you need to do.
So from that standpoint it’s easy to know how to get inducted.
Now it can (and should) take a fair bit of investment to get into the cabal. And that can be inflated a bit at the moment because you both have to do it and then catch scarab online if there are no mortal leaders.
I mean I was a leader and I turned away far more applicants than I accepted because people want that instant gratification. I was also surprised at some of the creativity that the process inspired, a level I have not seen in other cabals.
If you want to play the lone hero/villain against the world the way the cabal is structed is for you, if you want to be evil and get into a cabal quick... play empire.
