Manual of Exalted Power: The Alchemicals is a great step up from the first edition version. This time we get a book purely devoted to the Alchemical Exalted (who are solid canon, rather than an optional extra as they were in 1st ed). Gone is the series of dubious stories which you could use to integrate Alchemicals into your 1st edition game and instead we get more useful information on Alchemicals.
Two great martial arts are included (yes, we actually get to see Thousand Wounds Gear Style) and everything else that you would expect to see from the talented crop of freelancers that we currently have working on Exalted 2nd Ed.
I seriously recommend this book to anyone who is looking for something new to add to their Exalted games.
