Intel Officer: While attacking, after you roll your attack pool, you may exhaust this card to choose 1 defense token. If that token is spent during this attack, discard that token.
Effects use and Timing: p5. An “after” effect occurs immediately after the specified event and cannot occur again for that instance of the event.
Step 2 of Attack: p2. Roll Attack Dice: Gather attack dice to form the attack pool and roll those dice. Gather only the dice that are appropriate for the range of the attack as indicated by the icons on the range ruler.
Does the Intel Officer then get used in Step 2, rather than step 3? Most people seem to play him as part of the modify dice step, which if I have put this together with some semblance of logic would imply I have been doing it wrong with many others.
