besides the basic twf tree weapon finesse and point blank shot/ rapid shot than something that might make the risk of using chakrams in melee (that would be homebrewed though) i don't know what else to take. i know people say thrown weapons are not the best build but there is a difference between optimizing to be the best and optimizing to be good in the character specialty. for this character it be chakrams. i just don't know what feats to take. so some help be nice with this
