I'm really trying not to rush at this point. I've made it this far and I'd be pretty bummed if I did something stupid to kill Ironstevo now. I'm doing everything I can to try and make sure quests can be green in areas he's in. I'm also taking advantage of any xp that I can get from quests that pose no threat to Ironstevo such as the Noblegarden dailies. If he is still alive during Children's Week I plan on using those to boost his xp as well.
Ironstevo has also found a few rares since he's arrived in Outland netting him his Medium Rare Achievement and some decent xp (which you can see in the video below). He has been lucky enough to find a couple of Silverbound Treasure Chests as well, which give an absolutely insane amount of experience and a blue item.
