This is going to be the basis of my review for this product.
I'm giving debaing on a 5 star rating. But this might be because I was surprised by it.
Straight out, its a proody croonchy book,
25 pages of encounter tables
31 pages of adventure locations
53 pages of monsters
3.5 pages of magic items
1.5 pages of psionics
25 pages devoted to spells
7 pages devoted to equipment (includes vehicles, materials, and actual equip.)
23 pages of Prestige Classes* (more about these in a bit)
5 pages of feats
5 pages of slight tweaks to classes to make characters fit thier surroundings if they come from a frostfell area
8 pages on new races
30 pages on running a campaign in places where it can get below freezing.
Is there any information about running entire campaigns in frigid regions, such as Iceland Dale in the FR, or winter-themed spells or class variants?
The silver marches count as a frostfell area. So this book would be very useful for a campaign in Icewind Dale and similar locales. Just to give you an idea of the depth of the first 30 pages: "Iceberg" is listed as both a terrain feature and an ocean vehicle. This is great information if your characters get out in the Sea of Moving Ice. The monsters will be useful. The PrCs I would deem less so. As for the spells: If you got the Swords, this book's got the Ice Magic. The spells are very cool elemental spells. The locations are cool and useful also. Encounter tables, if they are your thing, are great. If not its a waste of space.
If I'm planning on sending the PCs on a trip to the great white north, but with a fairly tight focus, how good will this book be for me?
I don't need much in the way of new PC options, or even new monsters. I'd liek fancy environment stuff and the like (environmental dangers etc).
The first 30 pages would be of great use to you. They cover light in polar regions, frostbite, terrain etc. Equipment is a section I think you could also use. Everything else is character options. However, you will need to put together some NPCs in the region right? All the character options are good if you want to really flesh em out for the area.
The prestige classes in this book are hit and miss. There are 10 of them. However they are set up to be picked and chosen from rather than all dumped into a campaign. I really like the Frost Mage. This class gets a lot of goodies and might be overpowered a bit. However, to qualify for the class the character has to spend 24 hours in a blizzard with no protection, and survive. One class eventually becomes immortal. They will not naturally die. There is a Psionic Cryokineticist class (think BLIZZARDstarter), A class for a Norse setting, and a five level class primarily for barbarians. The rest seem kind of lackluster to me. I think Prstige classes should come in 7s and 3s. If you have more than 7, cull lit down to 7. If you have more than three you can probably cull it down to 3. If you have less than 3 you are probably ok.
I find Frostfell is an excellent campaign resource for anyone running a campaign in an area where the winters are described as harsh.
