It is hard to put a guard against every shenanigan players can come with. I dare to say that any system claiming to provide such a thing would be a digital-only work, or require a hand truck just to move the books around. So, yes, I designed the system assuming no player would try to abuse it. Naive, but a 200 words cap require some sacrifices.
Temporary consequences (yes, that was a typo, temporal is the spanish word for temporary. I mixed the two languages) are things that make a character life a bit more miserable for a short while, like a dislocated shoulder, o making a NPC uncoperative due a misundertanding. This is, something that goes away once you have time to take a look at it calmly. On the contrary, a persistent consequence is something that makes a character life miserable until they invest time and resources to remove it. A bunch of broken bones or a staggering debt to a loan shark would be nice examples.
