Nathema vet, last boss, second part, can't get it finished. Everyone dies but me, one guy stays rest quit while I am still engaged on the boss...
I SOLO the rest of the boss from about 75%! Scoundrel 70 scrapper
He compliments (BTW my first time doing that boss in anything other then solo) we then proceed to find the lore object, kill all the escaped creatures (achieve) and duo the light/dark extra boss pair. Great dude!
