Whoops, the missing d6-d8 cost is absolutely not intentional. You guessed right, and I must have just dropped that bit of text somewhere along the way, I’ll get that fixed on the website and in the PDF for the next update.
That’s a really good point about the starting attribute bump being a bit of a trap. I added that in the most recent version to give people more flexibility at character creation, but there’s absolutely an “optimal” choice, which is something I really want to avoid. I’ll have to think about ways to address that.
Really appreciate this feedback, and I hope your game is fun!
