Various new notorious monsters have been revealed for those not keeping up on the Lodestone updates. The ones discussed thus far are levequest NMs that appear to be temporary endgame content (the gear you can acquire is around rank 50). The gear you can obtain will certainly be nice IC additions for characters who are knights, pirates, or entertainers.
