One thing to note - because it's something people often miss - is "challenge declared" and "declaration of attackers" above are two steps in the same process of initiating/declaring/calling/issuing (whatever) an attack. The challenge cannot - and does not - begin until both things have happened. And, in fact, you cannot do one without the other. They cannot be separated.
The same is true for the "declaration of stealth" and "declaration of defenders" steps above. They are two steps in the single process of defending the challenge.
The description of "challenge resolution" above may be a little misleading, just because there is so much going on in it. To further break it down, you do the following (in order) when resolving a challenge:
- Determine the winner (by counting up and comparing the total challenge STRs for attacker and defender)
- Resolve claim effect (assuming the attacker won)
- Award "unopposed" bonus (if applicable)
- Award power for "Renown" to appropriate participating characters
- Resolve passive effects to any of the 4 things above (remember: Deadly, Vigilant, and other such keywords are passives)
- Starting with the First Player (no necessarily the person who attacked), players take turns playing responses to anything above.
One of the most important things to remember is that you cannot play any Response until you get to that last bullet point. The temptation is to play responses to winning/losing a challenge before resolving claim, etc. But instead, you wait until that "response" bullet point and then use response to all that happened before in any order. (The exception to this is any response that uses the words "save" or "cancel." Those are used to interrupt the resolution of each bullet point separately.)
