Picked Arkham Horror, Kingsport Horror expansion, and the Lurker at the Threshhold expansion up at GenCon; I love this so much (small wonder, it's a FFG boardgame!) that I picked up the Innsmouth Horror and Dunwich Horror expansions yesterday.
Teaching this to my boardgame group on Friday afternoon, and I have some questions that may very well come up. I'd prefer to have the proper answers the first time. 
1) When a player finishes his move at a location where they are able to turn in Gate/Monster Toughness tokens (such as South Church), can they turn in multiples at one time? Example: Lily Chen (Martial Artist) has three gate tokens and 5 toughness of monsters. Can she "Bless" four characters during a single Arkham Encounter step, or does this require four Arkham Encounter steps?
2) Mi-Go monster reads, "If you pass a Combat check against Migo, return it to the box and draw 1 Unique item". Is Migo effectively removed from the game if Mi-Go is successfully battled?
2a) Warlock monster reads, "If you pass a Combat check against Warlock, return it to the box and gain 2 Clue tokens." -- same question as #2.
3) Is Lily Chen's Martial Arts skill considered a "typeless" combat bonus? (IE: Not affected by Physical Resistance/Immunity or Magical Resistance/Immunity).
4) Are spells considered "Magical", and the bonuses affected by Magical Resistance / Magical Immunity? (IE: Dread Curse of Azathoth; Casting Modifier -2, Sanity Cost 2, 2 Hands, Any Phase: Cast and exhaust to gain +9 to Combat checks until the end of this combat.)
5) Patrice Hathaway gains 1 Clue token each time a gate opens. She also gains 5 Clue tokens when the 9th space on the Ancient One's doom track is filled. Will this result in a total of 6 Clue tokens when the 9th space is filled?
5a) The use of Marie Lambeau's Witch Blood special ability (Once per game, at the start of your turn, remove 1 doom token from the Ancient One's doom track), or the use of an Elder Gate, brings the doom track down to 8. Will Patrice Hathaway receive another 5 (or 6) Clue tokens when the 9th space on the Ancient One's doom track is filled again?
6) Charlie Kane's 'Connections' ability allows his to gain Allies that have been returned to the box. At current, is that the 27 total Allies that I have possession of, or only the 11 that started the game?
7) Physical Resistance / Magical Resistance: Round up, or round down? Example: Would a .38 Revolver (Physical Weapon; 1 Hand, +3 to Combat checks) result in a +1 or +2 modifier against a Physically Resistant creature?
