In the dream world you will come across rabbit creatures. In order to slay them you have to enter Sworcery mode by holding down your left mouse button on the player character. Once in Sworcery mode, click on one of the rabbits and hold the mouse button down. If highlighted correctly, the rabbit's head will shake up and down rapidly and after around 10 seconds you will hear the sound of a doorbell and the rabbit will explode. Simply repeat 7 times. You will get on screen messages after 3 kills, and again after 7 kills.
