Pyrrhus of Epirus' Helmet

Origin
Pyrrhus of Epirus was a Greek general who was an opponent of the early Roman Empire and became a ruler of Sicily. However, he is best known for the origin of the phrase pyrrhic victory. Pyrrhic victory is a term for which a person wins but at such a high cost that it also feels like defeat.

Effects
The helmet lets a person win anything, but when they take it off they have something bad happen to them in the near future. The larger a thing is won, like a lottery, the worse the trouble will be. If a person wins nothing while they wear the helmet, they will not suffer anything after they take it off.
