Posted this in another thread which I want to avoid derailing so re posting here:
"The set aside hit result cannot be cancelled by defence dice but the defender may cancel critical hits before it."
This reads to me that, I can cancel it with evade tokens or added evade results, just not the green agility dice themselves.
For example, if you roll a focus and a blank on your red dice, use FD to change the focus to a hit. I can just spend an evade token and avoid it.
However, if you rolled crit, hit focus, used FD to convert the focus result, I would have to generate two evades BEFORE I can declare use of the evade token to remove the FD hit.
With that being the case, most of the ships you want to hit with this thing will have evade tokens anyway. . ?
Read the FAQ under the Autoblasters or any "cannot be evaded" effect. It includes literally any form of evasion. Cancelling being completely different of course still works, though i dont think anybody has a die cancelling defense ability.
