I've accumulated an assortment of questions to post all at once so i didn't have to pester you all with them one at a time:
1) Are bonuses granted by attachments or locations like Alchemist's Shop considered "character abilities," or are character abilities only in the character card's text box?
2) Areo Hotah knelt with the banner attached to make him vengeful could stand due to a lost challenge, and kneel to activate his ability in response to that same challenge, correct? Without the vengeful attachment, i could not use distinct mastery after the loss to stand him and then use his ability, since i would lose the chance to make responses by the time i could play Distinct Mastery, right?
3) Am i right that standing a character that is participating in a challenge does not, in itself, remove that character from the challenge? For instance, if i use Distinct Mastery on Areo Hotah after he is declared as a defender but before the challenge resolves, does he still count his strength as a defender and is then available to use his ability after (assuming i still lost by 4 or more)? Or if i use it on Osmund Kettleblack to kneel him again to make himself a 7 on defense?
4) If the last attacking character is killed or returned to someone's hand, does that end the challenge without winners and losers, or is the attacker attacking with 0 strength?
5) If i let a challenge go unopposed, am i still the "defender" for purposes of card effects?
Thanks!
