Can certain card effects and events still trigger if you win a challenge on the defensive end?

What dictates winning a challenge on the defensive end?

Absolutely. There are a handful of effects that specify that you need to win as the attacker or defender in particular; but most effects merely state "After you win a challenge" and can be triggered after winning as either the attacker or defender.

You win a challenge on the defensive end when you have more participating STR than the attacker. You also win if the attacker has 0 participating STR, regardless of how much participating STR you have (i.e. Opponent attacks with a 0 STR character, you'll win the challenge without having to declare any defenders). Note, however, that if there are ever no participating characters left on either side of a challenge, the challenge ends immediately with no resolution (e.g. Opponent attacks with one character, you defend with one character, and then remove his character from the challenge [by killing, bouncing, whatever]--players will continue to take turns playing actions until both players pass and then the challenge will resolve with a winner; Compare to Opponent attacking with one character, you do not defend and then remove his character from the challenge--the challenge ends immediately and there is no winner or loser).

Not quite. If your opponent attacks either with a 0STR character, or you make it a 0STR character after declaration, if you don't provide a defense, you don't win. It's the same as if you defend with a 0STR character while they attack with a 0STR character. If neither side has any STR to count towards the total for winning, regardless of how many characters are participating, then the challenge is nullified with no winner.

Another question how do saves, duplicates, and things that prevent characters from being killed work with attachments? Do they come off if the character is saved?

It would depend on the save. Discarding a duplicate will not cause attachments to be discarded, but if the save effect causes the character to leave play (like come back to hand), the attachments would be discarded (unless the effect somehow saved the attachments too).

so then like bodygaurd would count as a save, but what about something like Power of Blood?

Power of Blood is a passive constant effect that makes a noble character [ring in bottom right] "cannot be killed," and is, therefore, not considered a save. A caveat, though, during that turn when this plot is revealed, these characters cannot be chosen to die for an effect that requires a target character to be killed or even chosen for military claim.

If a noble character is the only character on my board, then what do I do?

Note that a challenge with 0 STR on each side is still resolved (as long as there is at least one character in it). So passive effects that happen "after a challenge ends" (like Deadly or Disgruntled Mercenary) do happen.

Does Valor bypass Power of Blood when it comes to nobles?

i know just asked, but what if a noble iconed character is the only character on my side of the board?

futabaaoi said:

Then nothing happens to them. "Cannot" is an absolute in this game. If they have "cannot be killed" at the time something tries to kill them, then they cannot be killed.

ah ok, thanks for helping me with out. I'll be sure to ask again if anything else I do not understand.
