You need to use the ankou agitator on an ankou
before
you are in combat with it. If you use it on an ankou that you are already fighting (or which is fighting you) then you will get "Nothing interesting happens".
If done correctly, you will see the ankou say "AAACK". (I can't remember if this shows up in the chat box - it may only show in the actual game world display.)
You need to repeat this with quite a lot of ankous (though not a ridiculous number), and most of the time the "AAACK" is the only message you get. But eventually you will see "You feel your ankou agitator shake slightly..." and then a couple more messages as you make more progress.
