There's also a play session from the Dreamlands map up as well:
[edit: Also, not to be humble or anything, but I'm actually the one that set up the spreadsheet. Not that Afrofrycook hasn't contributed immensely to the CW community as it were, but I don't have much to brag about so I'll take what I can get. In addition the spreadsheet is open to anybody else and plenty of other people have helped to keep the spreadsheet updated]
Here is some information about the Dreamlands Monster Expansions.
SURFACE MONSTERS 1) Moonbeasts - 4 are available. Combat 0, Cost 1. When summoned, they sit on an enemy's spellbook and render it unavailable till they "fall off". They can be prematurely knocked off by spending Doom points.
2) Gnorri - 3 are available. Combat 2, Cost 3. Earn Doom points during the Doom phase.
3) Shantaks - 2 are available. Combat 2, Cost 2. They can move anywhere on the map, and when moving, can carry your cultist along for free.
UNDERWORLD MONSTERS 1) Ghasts - 4 are available. Combat 0, Cost 2. Unlike other Monsters, you get all four when you spend the Doom points. Also, when you spend the 2 Power to summon them, you get as many as are in your Pool (so usually no one does it unless they have 3-4 in the Pool).
2) Leng Spiders - 3 are available. Combat 1, Cost 2. Let you combine two Pains to make 1 Kill.
