Here is the scenario:
I attack intrigue with 1 character who has deadly. He blocks with a character with lesser strength with no deadly keyword.
Ok, now we are in the framework action where keywords go off. He chooses his character to die for deadly, then does a save reponse with maester of the sun.
Then he stands maester of the sun for vengeful.
I thought this was incorrect because the game checks for all the keywords (except renown) at the same time. So the game was checking for deadly, vengeful, stalwart, etc. But I deferred to him who said the game checks the keywords in the framework action when the keywords are available to 'go off'.
So does maester of the sun get to stand for vengeful?
