I'm just doing the elementalist/Hiberheim part through the witch's cabin at level 15 because I didn't find Marandino's Cave until after killing Mangoth, all the goblins on the map, the beginning part of the mines, the Troll King, etc. and all the spiders minus the queen. Probably a bunch more, but even that stuff was disjointed because I did it piecemeal. I'm sure I missed some important stuff because Mangoth came off as some sort of big deal, but I had never even heard of him until that chapel, and I read everything. I don't even know if I can get tenebrium weapons at this point, because I turned Sacred Stone against me while freeing prisoners and had to kill the tenebrium smiths. Ha, and I almost couldn't complete the Troll King quest because I picked up the tenebrium from the smiths and the quest log updated, but I couldn't offer Brandon that tenebrium in his dialog. And I hope I don't need that tenebrium for anything, because I put it down in a stack of 33 that I can't pick up, split up, or put in inventory, because it weighs too much.
