Yep, the difficulty die is what I was referring to. When we play tested it, I facilitated and just had the players roll the die. I could have rolled, bit the players seemed to enjoy rolling both (and it was faster). It is a natural fit for solo play too.
I also lean on AI when playing solo. It really helps when I get an odd Oracle answer or when I need some inspiration for situations.
Have fun! Oh, and if you're following CyberPunks, I will probably have an update later this week if I can figure out how to fix the imbalance.
