I didn't learn about my class upgrade quest until I am already 3/4 of the way through level 35. I am having trouble with Astray, like another poster posted

I get 2 shotted by Astray. Part of me thinks I should not be able to complete the quest unless I do it myself. Also, I am worried that I will hit level 36 before completing the quest and be unable to use the skill reset thingy. So, I have two questions: If I don't complete the quest, how can I get a skill reset thingy? I stumbled upon this quest because I wanted to reset my skills. My other question is, how ashamed should I be?

Maybe I will go beg for help in terminus.
