Boba Fett's re-rolling ability

By Orgapurius0907, in X-Wing Rules Questions

Ooooooooohhhh...kay.

Boba rolled 2 hits, 1 crit and 1 blank at range 1. 3 ties infront of him. Can he re-roll that blank die 3 times till he gets a good output? Does the same thing goes for defending aswell?

Thanks.

Any one die can only be rerolled once.
