Day 3 - Favorite Playable Class.
I know that some people don't like Psionics in D&D, I find them to be very fun to play.
My favorite class so far would have to be a Psion Shaper. They get a lot of the good powers that psions get, but they also get the power to create a construct that they can modify on the fly which can turn into a very powerful extra body. The construct is amazingly helpful damage wise, and also just being able to keep enemies off of the Psion itself as their lack of proficiency with armor, and their limited hit points make them quick to drop if hit much.
This class goes together well with the Kalashtar (my favorite race) in my opinion.
