If you end up working for the T'Rang, one of the quests they send you on is to lure a Rapax there to kill him.
You can buy a perfume from Crock in the swamp that you can use on the dummy to lure the Rapax into the area and to his death.
I killed him out front rather than to wait and see if their contraption worked LOL
