Random Character creation dice for use of NPC or even what the next character will be after an untimely horrific death are a specialty item. I was looking at picking up a set from a Canadian seller but they took long enough to get back to me that I still haven't heard from them and I've made a set.
This Class die as it sits I'm pretty happy with, depending on how you choose to ink it can impact how well it turns out, unfortunately for me the reddish brown resin that I used for the final of this die was a leftover of mixed standard ABS like Creality Resin.
I just did these up in Tinkercad
