by the way it's spelled kobold, can't really blame you cause the guy who started the thread spelled them wrong too and you're apparently a newbie. basicly they're these lizard men a little smaller than frodo from lord of the rings. They are basicly raised the same way as qunari from dragon age but to a more extreme manner considering that they put their children to work within hours of birth, and with a diffrent code of ethics that focus around trickery and loyalty to their clan. They also serve and worship dragons like they're gods and are relativly hated because of a stereotype caused by kobolds that worship evil dragons. If used right by a DM they can be down right scary.
Go monk, then be a badass Kobold. Remember you are badass, that's important, always remember that. Then punch dragons in the face because you are badass. Get Iron Armbands of Might. Continue being badass. Never use a weapon, always be badass.
Kobold Battlemind = Badass Heavy armor, tiny frame, big shield and oh yeah, you attack with your awesome constitution score, not strength like all those other surface dwelling lameheads. You are tough to the core and you got yourself there. No training at some fancy school, no following someone else's style, just you: and you rock! (I can imagine an over confident Kobold with a sarcastic steak pretty darn fun to role play.)
