Yep you've got it right. A knack is a specific situation that you gain +1 die in, and you should consider the setting when defining it. No point being a goblin basher if you are playing in a setting with no goblins.
And yes, if you roll two 6s before 4 you gain 2 Knacks, but it's important to note that Knacks aren't tied to your stats. They affect one specific situation or type (i.e. bashing goblins) but can be used with any Stat on any roll if it makes sense.
So for example, following the available setting, if I define “expert machinist” as a knack, I can use the +1 dice to any stat check involving tinkering with machine? Like persuading to trade an item with my repair service, or fixing machine in a hurry for survival, or operating machines in a fight etc? Is the die single use only or is it permanent?
Honestly before you say that the bonus die / knacks are not tied to any stat, my isntinct is to define a knack based on a stat
Also, will there be any new setting for the game?
