This may not be related to role-playing games. I'm going to try board games if it does not work.
Playing with my daughter's boyfriend, I realized this death. I asked him about that, but his son was a die, and he has no idea what it is for. Any ideas?
I observe that 3 and 4 are the average of a d6, 6 and 7 are the average of a d12, and 10 and 11 are the average of a d20. But apart from that I have nothing. Google has failed me … or I've failed Google.
Who knows where this dice is?
