Han Solo yt 1300 pilot ability

[Soupeey]

When using Hans pilot ability, how many times per round may you use his dice modification. 
 

obviously you can only re roll ONCE per roll (ie attack, defend, or obstacle resolution, you can only re roll once for each), but is there a limit per round on how many checks you can re roll? (Ie, re roll for obstacles and then attack and then defend, or just one of them?)

No, there is no upper limit to how many times Han Solo (Modified YT-1300 Light Freighter) may use his pilot ability in a single round.

Remember that "rerolling dice" is considered distinct from "rolling dice" from a mechanics standpoint, as such rerolled dice results do not trigger an opportunity for Han Solo to use his ability.
