When it says "the attacker cannot reroll the die changed by this card", does that just means abilities like Han's rerolls or a target lock? Or does that also mean if the attacker then uses a focus token, that one cannot be modified. Its says rerolled, and focus tokens aren't really rerolling.

It means exactly what it says.

You cannot re-roll the die that was affected by Sensor Jammer in any way (TL, Predator, Han, etc.).

Nothing is stopping you from flipping it to a hit result by spending a focus, using Chiraneau's ability, etc.

If that was the case it would use the language "modified"

Any die can only be rerolled once, but a die can be modified multiple times by the use of abilities, tokens, etc. as long as it doesn't include a reroll.

You might have an ability that changes a <blank> result to a <focus> result, then use a focus token to change that to a <boom> result, and another ability that changes it to a <kaboom> result. It still hasn't been rerolled, but it has been modified three times.

This may have been answered elsewhere, but how and when does this interact with R7? Can someone give me an "Order of Operations" for rerolling/modifying dice? Furthermore, Does R7 allow you to reroll dice that have been rerolled by a target lock?

Thank you

Both sensor jammer and R7 resolve during the modify attack dice step of the combat sequence. The defender chooses which of his two abilities he wants to use first.

Rulebook page 11:

If the attacker and defender both have abilities that can modify attack dice, the defender resolves all of his abilities before the attacker.

R7 resolves before the attacker can modify (i.e. use target lock) his dice.

Rulebook page 12:

... a die that has already been rerolled cannot be rerolled again during this attack.

The attacker cannot use target lock to reroll a die which was already rerolled by R7.

You know, I never considered that you can use R7 and Sensor Jammer both on an E-Wing.

As noted the defender will get to choose which order to resolve these two triggers. If the Sensor Jammer is used first then R7 will NOT reroll that die. Strangely, if R7 resolves first then Sensor Jammer can then be used to modify one of the dice that R7 had just re-rolled. Note that the attack will not be able to re-roll any of the dice touched by R7 or the Jammer.

Oh wow. So unrelated to sensor jammers, a die can only be rerolled once? So Han with predator wouldn't interact too well then? If he enacted Predator to reroll a die, and rolled a blank, then used his pilot ability, he wouldn't reroll the blank one a second time?

In fact, if he did this, he'd be forced to re-roll everything except the blank one he had already re-rolled. 'Cause Han.

However, Han and Predator still work well together.

Normally, if you rolled 1 boom, you'd only be able to reroll 1 of the two blanks to get a max of 2 booms. However, Han says F that, and rerolls all 3, hoping to get an overall better result. In this case, he does not use Predator. If you rolled two booms though, you'd be hard pressed to want to pick up those two and the blank in order to see if you can roll 3 booms with Han's ability. At that point, you use Predator in order to reroll just the one die.

There are also fringe cases where Han will use Predator and then his ability. For example, if you are at R1, and you get 2 booms and 2 blanks, but you know you need to do 3 damage, you would first use predator to reroll one of the blanks. If it fails to produce the 3rd blank, you then use Han's ability to hope that you get the 12.5% chance of rolling 3 booms. An instance of this would be going against an auto thruster Fel w/ Evade token, or another Fat Han, where 2 damage is instantly mitigated. Sadly, this is more common than you would think.
