hey guys,

Ok, this has been bugging me for awhile, but skills like Marksman, which say i can re-roll a specific check, how do they work exactly, do i re-roll ALL my dice, including successes, do i get fresh dice on my failures, do i get ALL my dice back and keep my success, or something else? currently i've been going with re-rolling my failures much like Mandy Thompson's ability.

I think it's supposed to give you another chance at passing a failed test, and you roll all of your dice for that test. Otherwise it would specifically say to re-roll any failures.

you reboot entirely, nothing is saved, you just get another crack at it.

Also note, that clues ADD to the number of dice rolled. So if you use the skill for a re-roll, you also get to re-roll the dice gotten from clues used before activating the skill.
