So I have a problem..

So I have started to notice that as I am running the clockworks, specifically at this time JK runs, I have not been getting many of the materials picked up. It seems like everyone else in the party is getting something pretty much every time and then i get one here or there. Is there something I can do to increase my chance of getting items picked up by myself or others or am i just screwed and not one of the lucky ones in the game?
One other thing is the prize wheel I only seem to get low amount of coins and maybe a heart or vial but never anything else. Anything I can do to improve this? Thanks!

To get more materials, adventure in smaller groups. To get better prize wheel results, try to finish a floor with full health and a full pickups bar; that way you won't get hearts and pickups.
Beyond that, it's just luck.

Well that is disappointing to hear. Wish that were not the case but I guess I am screwed then.

Last time I checked all party members get the cumulative amount of crowns from the prize wheel. So if you get 5, Bob gets 10, Noob-Zilla gets 50, and Why-Rum-Gone gets a vial you all get 65cr.
That is unless it has changed since I last checked. If that is the case disregard this post.

Not that I know of. Everything is random so you're just really really unlucky.
