I need a Professor New Foxy Chest Plate for about 318k. Is it worth it? I have literally no perspective. (25 min left)

I personally wouldn't do it, but there is still a chance to make up for the losses in the next few quests. Things really heat up once you get to level 71 and then get absurdly hard at level 91, where he can ask for items that are practically nonexistent.
