I went through the official answers by FGG, but could not find anything on these (very specific) points:
1. Can a dark charmed hero attacking himself spend valor tokens for his defence rolls through Glory of Battle?
I think not, as he is treated as a monster for this attack.
2. Does a dark charmed Stalker hero attacking himself benefit from an adjacent trap token (Set Trap) during his attack roll?
3. Is it possible to play Dark Charm twice (on different heroes) during the start of the turn phase? I think, if the OL has 15 cards on his hand, Dark Charm is directly redrawn when a hero passes the test or a hero is defeated by the charmed hero. Therefore it should be possible.
Maybe some of the rules experts around here (yes, I am looking at you Dr. Zaltyre ) can help?
