Zenith crown..dropped off byakko and genbu only.
Requires A. Abj. hd. and cursed crown. You have to take it to the church in northern sandy and trade it to the guy by the bookshelf in the manuscripts room. The mitts are dropped off genbu and fafnir. The pumps off fafnir and king behemoth. The dalmatica off nidhogg and aspidochelone. The slacks come from suzaku and byakko.
Cursed zenith gear (besides mitts and crown) is very expensive to make because it requires siren's hair which on carbuncle server runs about 600-650k usually and the pumps and slacks require siren's macrame which takes 2 siren's hairs to make. orz. The mitts and crown don't cost as much. The dalmatica runs about 3-4 million to craft >.<
