Bracers are pretty much BIS for her accessories, Amelias Apron and if not that then Demon mail or anything with flat atk, Helm is Black Cowl, TM's anything that boost atk (these will be atk+30%, power of creation, etc. ) oh and also lvl her LB if you can as its great aoe damage.
Also one of the trials drops a bracer equivalent, to help you out. Really, just with her own tm and doublehand, shes beastly.
Grats sas.
