ok so you get to the encampment with the lvl 35 elite orcs. once close enough you get a message telling you to use the stone. Use it but don't charge the baddies yet. step closer little by little until you see your health bar change.. your character will have wind blowing in front of them at this point and now just wait for you health bar to fill back up. You should have around 6k hp or so. Now you're ready for the quest. Kill the non-archers first as they do more damage, but try to stay close enough to the archers so they dont shoot arrows while youre killing the non-archers. I think that the inspiration buffs have a time limit because when I finally was getting close to the boss , I lost my inspiration buffs.. when they wear off you have a debuff called exhaustion that prevents you from using the inspiration buffs for 30 minutes. So guess I will try the quest again in 30 mins.
