This isn't really a review, but I got this and adventure thought I'd share some non-spoiler info after reading it through (for some reason I don't like to play off of pdf files, so I'll be waiting for the print version to arrive to play it- and we're using RoSD material as a basis for our own ongoing non-RoSD campaign, so I probably won't be playing it 100% as written, but our game will probably lean heavily on the scenario).
Anyway, the set up is that several important jewels have been stolen, and you are on the trail of one of them. This takes you to a house on the edge of a cliff, which has got a lot of spiders that aren't friendly. You have to fight your way through to get the jewel (and any other points of interest along the way) and get out. There are two scenarios- the house interior, and (hopefully this isn't too SPOILER-y) what I'll call the spider's lair.
For a complete set of miniatures you'd need: a couple of giant rats, 2 spider swarms, a bunch of giant spiders that you can classify into three groups (could be by markings, color, size difference, etc.), a bunch of zombies, a giant worm, and a spider boss.
The scenarios have ways of upping the difficulty level for higher level Rangers, which is cool, so players of any experience level should be able to enjoy a challenge.
It looks like a really fun scenario and I find the mission inspiring even if we're probably going to tweak it for our own nefarious campaign! I'd love to hear anyone's thoughts who have had the chance to play it. Also the set up makes it appear that more scenarios will be forthcoming to continue this story, so that's something more to look forward to!
