In the item description of the mirror of opposition, it says "Upon the defeat or destruction of either the duplicate or the original, the duplicate & her items disappear completely."
I'm still learning about the rules of the game & I would like for anyone to help me by defining what a "defeat" is. I wouldn't think it would mean death, because then what would destruction mean? I just want to be clear on what status changes constitute a "defeat" by definition. Thanks for any input on this, I have no experience with actually getting to play a character, so I'm trying to get understanding about what experienced players have to say.
