"There shouldn't be a point where you are grinding a specific skill for more than a few runs" - then it seems like I'm missing something pretty fundamental. Possibly to do with Potential? Should I be spending my rounders on Patience and Perception, rather than holding onto them for the extra time?
The tips say overlapping skills are literal, which probably has something to do with Meditate (as the only non-gold action that shares skills with other actions), but either way it's not useful unless I can unlock a way to "store" "points" in the formation thing.
