The KO method I have been using instead of trapping it or using bolas is holding it with a megalosaurus and having one of my friends shoot it with tranqs. Sometimes the Ravager is able to hit the megalosaurus so if you do this then you might have to adjust your camera angle until the Ravager isn’t able to hit you + I haven’t been able to dismount a megalosaurus without dropping the Ravager. A thing that I have found is that if you are holding the Ravager and it is hitting me, going into water messes with it and for some reason it isn’t able to hit me as much.
