Can someone work me through the steps for when I attack first with a Sensor Jammer on my ship and when someone attacks me first with a sensor jammer on my ship.

Thx

Alright, so when the ship with a Sensor Jammer attacks, nothing special happens. It is exclusively a defensive upgrade. However, when you attack first, they may choose to spend their focus token to avoid damage, depriving them of its use against you. Or they may not spend it, taking more damage, in order to avoid the Jammer.

When you are attacked, here are the steps of combat:

Declare Attack

Roll Attack Dice

Defender Modifies Attack Dice

Attacker Modifies Attack Dice

Defender Rolls Defense Dice

Attacker Modifies Defense Dice

Defender Modified Defense Dice

Compare Results

Resolve Damage

In the case of the Sensor Jammer, it impacts the 'Defender Modifies Attack Dice' step.

So, the attacker with target lock attacks. He rolls Blank, Focus, Hit, Crit.

The defender gets to modify first, so he changes the Hit into a Focus. Of special note, this die cannot be rerolled as per the rules of Sensor Jammer.

The attacker can now modify attack dice. He spends TL to reroll the Blank and one Focus (the second he can't). He gets a Hit and a Focus. The final result is Focus, Focus, Hit, Crit. Defender can then roll dice to avoid damage.

Of particular note, Sensor Jammer cannot change Crits. Let's say an attack with TL rolls attack and gets the following: Blank, Blank, Focus, Crit. The next step would be defender modification. There is not hit to change. The next step is attack modification. He rerolls Blank, Blank, and Focus and gets Blank, Hit, Hit, Crit. The defender cannot change these with Sensor Jammer. That time has passed.

Thank you
