After having done some research on its cultural significance, I learned that the 5 yen coin is supposed to represent luck. And after having gone through a game of Warframe trying to help a buddy get a piece to one of the in-game armor systems to no avail, I decided to TEST that theory, and keep it in my hand while we made another crack at that piece. Instantly got it. Works...as...intended.

Yeah, they're potent alright. Not quite my cup of tea, but I'll charge on ahead and consume/chew them all. I got these out of my Dekabox today, and they are NOT for the faint of heart.

The one star reduction is simply because they're a little too strong for my taste. Otherwise they are quite fun.
