god damn, i really want this. so far i've made the regular adaman celata and adaman sollerets, i'm just ONE ADAMAN CHAIN away from crafting the cursed hauberk. i'm seriously hoping for the armada because there's a guy on our rival linkshell with the adaman, and we always like to show them up, so if i can get the armada hauberk, we can really rub it in their faces!
When you synth cursed gear, sometimes you'll get a lucky synth and get a -1 piece. In this case, this is from the Cursed Hauberk -1. As with the normal Cursed Hauberk, you must obtain the necessary Abjuration, give the Cursed Hauberk -1 and the Abjuration to the NPC in the Sandorian Cathedral (I forgot his name), and the -1 Hauberk will become a +1 Hauberk, i.e. the +1 of Adaman, which is Armada. I believe the Abjuration for Cursed Hauberks is dropped off Nidhogg in Dragon's Aery. Happy Hunting!
