I'm looking at possibly pairing an E-Wing with an R7 astromech and Sensor Jammer, and wanted to see if this made sense or if they are redundant (I know the reroll restriction is).

My assumption is that, based off the text for both

"Once per round when defending, if you have a target lock on the attacker, you may spend the target lock to choose any or all attack dice. The attacker must reroll the chosen dice."

"When defending, you may change 1 of the attacker's hit results to an eye result. The attacker cannot reroll the die with the changed result"

Thus,

1. Attacker rolls four dice. Three hits, one blank.

2. Activate R7 and choose the three hits to be rerolled.

3. Attacker rolls Hit, Hit, Blank, so now the full set is Hit x2, Blank x2

4. Activate Sensor Jammer to change 1 of the Hits to an eye.

Would this be accurate?

Thanks!

Seems correct to me.

That is correct.

You may use R7 and Sensor Jammer in any order you like. So you are allowed to use SJ first and R7 second. If you want to.

Yeah it works, because R7 is a re-roll and Sensor Jammer is a change. You can both re-roll and change the same die, in fact you can change a die any number of times, you just can't re-roll them again.

So when do you user R7?

Before or after you roll your defend dice?

I assume after so if I roll Blank blank evade I can get you to reroll and use what I rolled in the new roll?

So when do you user R7?

You have to use it, and Sensor Jammer before you roll your defense dice. Here's the steps in order. This is covered on page 11 and 12 of the core rules.

1. Roll Attack dice
2. Defender modifies attack dice
3. Attacker modifies attack dice
4. Roll defense dice
5. Attacker modifies defense dice
6. Defender modifies defense dice.

Ahh yes

Thanks

Also remember that the attacker can not then reroll the attack dice that you rerolled with R7. A dice that has been rerolled can not be rolled again. It can be modified, but not rolled.

So Sensor Jammer will be quite useless as long as the attacker has a focus token available since the attacker uses his focus after Sensor Jammer does it's thing?

That all depends.

If they have a single <focus> then is it worth using the token? If they do, then they don't have the token for defense, which can be reason enough to use it, just to get them to burn it now.

If your opponent is already planning on using their focus token, then yes.

However, if your opponent doesn't have a focus token (for many plausible reasons), then they're screwed.

Moreover, if they wanted to use that focus token for any other reason (like, say, not letting you use Opportunist against them), they're screwed every way imaginable.
