So we've played three games since I got Descent last week, and have had great fun, made some mistakes along the way, and encountered a handful of rules questions as we've done it.
First one that is of most immediate concern is, do the Lair of the Wyrm quests such as Gold Digger, Rude Awakening, and What's Yours Is Mine award one xp per player at completion?
Unlike the Shadow Rune quests, those quests don't specifically mention an xp reward in their reward block. However the main rulebook, page 20, step 3: Receive Rewards makes it sound like 1 xp is always rewarded upon completion of a quest.
Admittedly the way the main rulebook and quest guide is written, we almost thought players were getting two xp per Shadow Rune quest, but we came to our senses after some quick math.
Next is a monster question: Master Cave Spider - Web: Do heroes have to pay one fatigue to move out of each and every square adjacent to the Master Cave Spider during their movement?
For example a character attempting to run past a Master Cave Spider in a two square wide corridor (a hallway for instance) would end up paying a total of three fatigue to travel through the three squares adjacent to the spider in order to get completely past it.
Is that correct?
And one more monster question, this one we think we've already worked out via the FAQ, rulebook, and forum, but we'll restate it here for feedback. Flame Breath (and similar powers). As we understand things, it can trace its path around corners and through obstacles like boulders (but not doors) because LOS is irrelevant to it since it is not implicitly stated to require it and it's not actually moving in such a way that obstacles would impeded it.
