Hello,
I can see that the Dunwich Horror can be very, very nasty and He can pretty much take a player out pretty easily. My concern however is in regards to one of his Combat Checks for a specific card. If you fail a combat check you lose all of your items on one of the random cards you draw before you face him. So what does this mean? A) are you able to sneak from him at all? B) if you lose all your items and you keep failing and you have no items how does combat end if he really does not damage you? What happens when facing this scenario? Thanks for your time.
, Kevin Wilson's (which can be found somewhere on these boards) has made the rule for how to deal with it, so you do not need a house rule.
