1: Hero Attacking - If the Hero does not deal sufficient enough damage to deal any hearts to a monster, may they still spend their surge to recover fatigue?
Ran into a scenario where the Disciple was completely fatigued, made a move, made a successful attack which dealt no damage, recovered a fatigue using a surge, and spent the fatigue recovered to; Holy Power -> Prayer of Healing -> Cleansing Touch, removing conditions from themself and an adjacent Hero. Disease on the Disciple - (which afflicted the full fatigue upon the start of that Heroes' turn), and Immobilize on the Berserker - (with the intention of preventing an attack for a full turn)
I've looked around, and there doesn't appear to be any indication that this is or isn't allowed. I think it should follow the same rules as applying conditions, which generally require at least one damage to be dealt.
2: I got a little greasy on the Finale playing the Overlord in the Shadow Ruins Campaign, although I did handicap myself slightly to give the Heroes an advantage. The player controlling both Heroes certainly didn't find me laying 3 traps on a single Search very appealing. (I had actually planned to run back past the doorway, close the door, and lay the traps on the door - but he decided to Search instead of approaching the hallway.)
Poison Dart, Uthek's Demon Trap, & Exploding Rune on the same Search token. Following the rules, for the use of Overlord cards, they must not have the same name, on the same figure, with the same triggering affects. They do not have the same name, but may they be used in conjunction with each other on a single search?
3: May you use a Lucky Charm accessory during the Travel Phase? If yes, is it refreshed prior to it's wearer's first turn?
4: Overpower (Sir Alric Farrow): If you successfully Overpower, and trade spaces with a Hero, may you place a trap on that Heroes' new location and does it trigger?
