For a warrior, you're gonna want a few creations with you (though its probably a little to late to really change that now) at all times. Wear heavy armor to shake off damage. Make and use artifacts. There are books scattered throughout the game that can tell you what they are and what they do. (Alternativly, you can see the list of artifact ingredient locations on the thread "Strategy Central" at the top of this page.) I personaly work well with the belt that increases my Shaping skill, and the boots that increase my AP limit. If you're working for the rebels, they its perhaps time you consider joining a faction. Astoria gives training for upper-tier creations, and Ghaldrig gives you access to Drakon/Gazar canisters, who are in my opinion, the most powerful creations.
From the looks of it, you seem like your still in the Storm Planes/Wasteland area. Consider moving down south to the Dera Reaches, to have a fresh new area to work with. And most importantly, do NOT kill the Unbound just yet. If you want to try to maximise your characters potential level, kill them around level 46-8ish. They still give experience while very few other enemies still do.
