## The order the roll resolves in

An attack in Imperial Assault rolls attack and defense dice at the same time, but resolution has an order. First check accuracy: in ranged attacks, total accuracy must reach the distance in spaces to the target, otherwise the attack misses entirely regardless of damage rolled.

Once accuracy is met, surges are spent on card abilities, which can add damage or apply effects. Only then is the result compared against defense: block reduces damage, evade cancels surges and dodge negates the whole attack.

The white die's dodge is the harshest case: it cancels the attack completely, no matter how much damage was rolled. That is why the roll must be read in order rather than summed all at once.

## Frequently asked questions

### What does the Dodge (X) symbol on the white die do?

The Dodge symbol cancels the entire attack, causing it to miss completely regardless of how much damage or surge the attacker rolled.

### How does Accuracy work in ranged attacks?

In ranged combat, total rolled accuracy numbers must equal or exceed the distance in spaces to the target, or the attack misses entirely.

### In what order do accuracy, surge and defense resolve?

Accuracy first, which can make the attack miss outright. Then surges are spent on abilities. Defense applies last, with block, evade and dodge.

### Does accuracy matter in melee attacks?

No. The distance check applies to ranged attacks; in melee the target is adjacent and accuracy is not compared.
