I agree using the light to kill the knights is still killing the knights..... but they detonate corrupted light so obviously we are suppose to kill them (after the ogre) before they detonate corrputed light. If we werent intended to kill nights before corrupted light detonation they wouldnt even be there. The events play out like this because we were intended to do it that way. A ogre spawns, you kill it to get corrupted light. Knight comes out to detonate, kill him so he doesnt. Oryx staggers, go detonate corrupted light. By leaving ogres alive, you dont need to worry about knights pre-detonating corrupted light. slow clap
