This happened to me today. Ray attacked, I had a Target lock on Ray with M9-G8 she rolled 2 Kabooms. I modify using the Astro she rolled a blank using Ray's ability can she reroll the blank she rolled with M9-G8?
M9-G8 vs Ray with Finn
No, each die can only be rerolled once
So, in other words, you got the perfect result out of 'Gate'.
Yeah, that actually saved my ship. I was using an ARC 170 and no shield's.
