Review by Malwing

Oh god. I wrote an incredibly long review that the site ate. Here's the short version.

Bottom-line, five stars. There are a lot of good archetypes, a good alternate class, and other options that inspire new characters for me and is well worth the price.

Some of the archetypes pull Cavalier from being a mundane class.

I'm wary of the Briar Knight because I see it's Tanglevine Strike as insanely powerful especially since he apparently gets armor that doesn't appear to give an armor check penalty or reduce speed and grants up to a +17 armor bonus but that's arguably powerful since it can't be enchanted.

I'm unsure as to what's going on with the Formation Rider's ability.

Other than that I saw no real glitches. Nothing terribly weak or overpowered. Granting it five stars.
