Using the Tome of the Cabal, summon and subdue a felhunter, then return the Tome of the Cabal to Strahad Farsan in Ratchet.
If you're are sufficiently prepared, then we should begin. Let me explain the process to you.
I will begin by creating the basic summoning circle. When that is finished, my acolytes will use the rods of channeling to create the greater circle.
Once that is done, read the incantation from the Tome of the Cabal, and the felhunter will be pulled forth. Be careful, [player]. A felhunter is a powerful foe, and I'd like to see you keep your head on your shoulders.
