Alright, so I don't have wave 3 and currious about how this build would work. Lets start with saying I'm using

Trelix in the Firespray w HLC and APT

Cpt Jonus

lets ignnore the rest.

So if Trelix uses a secondary weapon, the pilot ability allows to re-roll 1 die. If Jonus is in range 1, another 2 dice can be re-rolled. How exactly would you resolve this? ICan you say re-roll 3 dice at one time? Could you re-roll the 2 and then 1 of those 2 if it didn't produce the result you wanted? Can some one clarify for me?

You can only re-roll dice once per attack/defense. So if you have the ability to re-roll 3 dice, you can choose up to 3 to re-roll once. You can still use focus and other abilities to change them, just not re-roll.

Thanks buddy
