On the last level when you meet Liana, she will start fighting the Goblins. There will be an unlimited amount of them. If you need to level up, stay there for awhile and collect all of the courage points. Also, in the last level (Gathering Of The Clouds), when you meet up with Lianna, you can get endless courage points by either waiting at the top of the ladder for Lianna to kill all of the Orcs, or by fighting them yourself. The Orcs will keep appearing, supplying you with endless courage points.
