Adds a new dimension to the basic game: This set of rules allows you to go on a quest rather than searching for a finale room. It also contains rules for two-player parties.
Again with the spelling errors? (rolleyes) "Alter" refers to a change of some kind. "Altar" refers to the big stone thing priests pray at. Really five seconds at dictionary dot com is all it takes..... (Don't even get me started on the "Chaple" in the Forest Quest Cards)
Overall, you get a good value for the money. Definitely money well-spent.
