Looking at the monster stat blocks again, I think I've found another minor quibble with the system. I think I'm up to 4-5 extremely minor issues now. That's kinda fantastic, I think.
The monster attacks spend a lot of words repeating things like "does not take your action" after forcing you to make a roll. If only there were some easy to use game-speak term to save them from having to write out "make this kind of roll as an automatic and free reaction when faced with this circumstance" dozens of times.
I don't know what that phrase is, but I'm sure it's out there somewhere and would save them time. (Yes, that's sarcasm.)
It would save maybe 100-150 words across the rulebook and Bestiary. But it is kinda silly they waste them.
