After I got the items (lvl 45) in this quest I just discarded them because I have better Gear at the moment.

The problem is that I need them to talk to Alka Zolka and finish the quest and now I'm stuck because:

1. I can't 'Abandon' and retake the quest.
2. The Calamity Salvager don't sell the SCH job equips yet since I did not complete the quest.
3. There's no other way to acquire the Scholar's AF right now.
