Black Fairy Dust

There is one recipe this feeds, a wing pair, so the only real question is how many Pumpking kills it takes. The chance improves the deeper into the event you are, which means a Pumpkin Moon that stalls out in the middle waves is close to a wasted night. Build an arena that can hold the late waves before you start counting materials.

If you have no use for the wings themselves, craft them anyway and sell the finished pair. Assembled wings are worth far more than the loose parts that went into them, and the gap is wide enough to justify the extra step.
