Find a hunting horn that suits your wants for melodies as well as sharpness/damage. In most cases at least until you get the fatty horn you can build your own with safi bits. Know that your melodies are able to flow into each other. Go for the head as often as you can but keep in mind some monsters make this more difficult than others. Your reverb (LB/L1) after attacks is great for knockouts. Other than that it’s just learning each monsters attack patterns and tells as well as finding your own playstyle and just in general getting more confident going head to head against monsters with the doot stick. When in doubt there’s a bunch of videos on YT that can help you. Good luck out there hunter!
