Day 5 - Favorite Set of Dice/Individual Die
I've owned my favorite die since my sophomore year of high school. It's a "bone" d6 that I bought on an honor's field trip. This is the same trip I met my good friend Josh on (and when he finally took the plunge and bought his first D&D book). I know it's just a d6, but it looks awesome and I've got a lot of use out of it. It's my d6 of choice.
My "Yellow Sign" d10 and "Miskatonic U" d6 get honorable mentions, but I haven't had them as long, so I haven't got to use them as much.
