[Bozos of Bones]

Do not focus on any rogue feats, they don't worth bupkuss. Except maybe envenom weapon, that one is usefull on thougher enemies. Once she drops entangle on herself, she should morph into a wild shape and tear the enemies to shreds. Do not take feats for other wild shapes, but you could take extra wild shapes per day. When attacking in normal form, go for the bigger enemies, where the halfling's racial benefit should be most usefull. I don't know if this racial bonus is kept on wild shapes, but I doubt it.
