For a successfull kill of Jhen Mohran you need a good party. If you have no idea what to do, than the best thing is to constantly grab canon balls and fire them on him. And hope that the other team members know what they do ... 
If you are really lucky, than you can get elder dragon blood and earth dragongem which are necessary for some weapons. However, it may be easier to get elder dragon blood offline from the ceadeus.
