We are starting a new group, new world, new GM and I was looking at making a Yuan-Ti. I am looking for suggestions on what classes would be good. I am compleatly open to all suggestions. Thanks in advance.
Monk. See Dragon #310 for variant monk "Cobra Style" and "Hunter Monk" option to get Ranger's Favored Enemy (humans). Use your natural fangs and flexible torso to wrap around foes and bite them. Great fun!
Flavor-wise, I'd go with a druid or a cleric with the Animal and Scalykind domains. Munchkinwise, ECL rases pretty much suck for casters, so I'd probably go with the ranger or monk ideas.
