I got two small rocks for finish 7 quoins shy of being an apprentice hero. Cracked them open and got 100 currents and 50 currents. I'm feeling a little underwhelmed. I will not be going out of my way to participate in the next feats. Feel kind of dumb sacrificing sleep for 150 currants. Should have kept the rocks.
Edit: OK, rocks are much better now. Way more satisfying to crack one open and get some beads to trade instead of currents. Thanks for the fix Tiny Speck
