The encounter of this installment, complete with a little map, takes up 3 pages and once again features a new creature, a magical beast cat-creature that is quite simply one of the coolest CR 1 critters I've read in quite some time. The encounter also comes with an artwork of one specific feature of the dungeon that will have PCs wonder or at least pause for a second.
After the encounter, we get a 2 page-replica of the introduction to the Ruins Perilous some may already know from the first installment.
The map-part starts with the cover and a quick how-to. (2 pages) It features a one-page map of the encounter as well as a over-blown version of the map for use with miniatures that takes up 8 pages. There is also a printer-friendly b/w version of the miniature-friendly map that takes up the last 8 pages of the pdf.
Editing and formatting are top-notch, I didn't notice any mistakes. Layout of this full-color pdf is once again beautiful and the maps are up to the high RiP-standard we know from the ECS-line. Only that around here, they are in color. The encounter presented here is more complex and intelligent than the one in this files predecessor and thus also more rewarding. While the encounter didn't absolutely blast me away, I have to consider the low price and the intention of this product - It succeeds at its intention and is very cheap and thus my verdict will be 4.5 stars, rounded up to 5 for the purpose of this platform. If you don't plan on using the maps, detract a star.
[4 of 5 Stars!]
