When Dracarys is played, could you play a card to save that character such as something to add strength? From what I have been reading through various interpretations of the rules, it all matters on who plays what card first.

For example. If I am defending as the nights watch and during a military challenge the character I use to defend is hit with Dracarys, I could use the wall to boost his strength by 2 when I kneel the wall. Am I correct in this assessment? I know since dracarys was played first those effect would diminish before the added effects of the wall. Now if I played the wall prior to dracarys, once the effects of the wall are gone I believe the brun effects are still there and that character would be killed.

Is this correct or am I misinterpreting this card.. (if so holy .... that card sucks lol).

Sorry I mean Castle Black not the wall

Once Dracarys! is played and a character reaches 0 strength, it is too late for any Action to keep him alive. Only an Interrupt that both stops the death and raises his strength above 0 can keep him alive (such as Risen From The Sea on a 4 Strength Greyjoy Character).
