Could anyone reccomend me a Hermit skill build?

It would be more helpful if you were to give more information about your playing style. The build provided above is great if you like to have some extra skills to play with, and if you like the mobility granted by Flash Jump. However, if you want to move on to higher-level monsters sooner, you'll be shafted a bit by that build as you won't max Shadow Partner as soon as you should.

My personal build has gone, and will proceed, in this fashion:

As you can see, I chose to forgo Lv1 Avenger at Lv70. Personally, I chose to do this because Avenger did not show any use for me at that point. If you are training in an area where you will benefit from it, feel free to put your first point into Avenger--you'll max Shadow Partner at Lv80 either way.
