Gaming with my daughter's boyfriend, I noticed this die. I asked him about it, but his tl;dr was it was a found die, and he has no idea what it's for or from. Any ideas?
I do note that 3 & 4 are the average of a d6, 6 & 7 are the average of a d12, and 10 & 11 are the average of a d20. But other than that I've got nothing. Google has failed me... or I have failed Google.
Who knows where this die is from?
