I found a good way to get exp and gold but it requires a dragon amulet sorry guys.you have to talk to nythera and take the storm war quest(if u dont have it u have to do the quest the storm)take the titan battles and put your dragons element to their weak element since my dragon is fire i fight the water titan and its pretty easy if you fully trained your dragonrider armor i just keep using stun burn mega burn and breath and heal if i need to and when u win you get 2000exp and 300gold for 1 fight
