: skillmonkey PrC with water themes.
: Soulborn/Shadowcaster gish.
: Incarnum using PrC for lizardfolk.
: class based around not fighting. Probably not useful in a standard D&D game.
Scion of Awesome
: You're so cool you make the universe forget that you shouldn't be able to do that.
: As it turns out, some undead don't need to be all in one piece to be dangerous.
Channel of Ysgard
: Incarnate PrC which is viking themed.
: Warforged PrC based around executing your battle plan.
Another Incarnum PrC, this one combines Factotum and Incarnate. There is also an epic destiny involved but... friends don't let friends play Epic.
Master of Marks:
A skill based class which creates supernatural effects with runes. Most effective if given the chance to prepare a battlefield, an ambush, a robbery, etc ahead of time.
Turns money into power without the bother of magic items. Comes in direct engagement and manipulator/summoner varieties.
: A ranger oriented PrC with various abilities to help v mythical firebirds.
: Warlock/Ninja hybrid, with the goal of making it easier to make ninjas from the movies using the ninja class.
: It's like Combat Focus, but less terrible.
: It's a caveman wielding a club that is also a psion. Not the caveman, the club.
: Remember the Helm of Brilliance? This class makes it... less stupid to use.
: It's a bard who tells people that monsters aren't so scary. And they have powers to make it (sort of) true.
: Mark of Justice is normally a problem. This class makes it an opportunity.
: Have you ever wanted to purge evil with your fireballs, but your party members keep getting in the way? This class is for you.
Adept of Loki
: Did you ever think that D&D needed more dice? This class has you roll for class features every level. And BAB, saves, skills... it's probably not a good idea to actually play it.
: It's a fighter. With a dash of Favored Soul. Also it gets outsider powers and turns into an angel... or a devil.
Scout PrC that lets you make an area of the battlefield more interesting. Attack and movement choices, and something about knowledge I guess.
Pilot of Nothingness
:Class based around calling a giant fighting robot.
: it's full BAB and full meldshaper level. And gets essentia from level
Another Incarnate Soulmeld
: much more effective at healing than Lifebond Vestments.
: most of these are useless for Archivists, which is good or bad, depending.
Human Paragon Substitution Levels
: includes a vestige based on Theodore Roosevelt.
New uses for Sense Motive and Gather Information
: exactly what it says on the tin.
