Alright, since nobody seems to have posted any real info, here ya go.
Note the shield at the bottom, Aegis. Here it is in the model viewer:
I'd this is one of the relics everyone's been talking about. Enhances "Shield Bash" effect, and I think that says Physical Damage down 25%.
And... The rest of the armors that I know of, with body armor stats for examples.
The ones you've seen.
Unicorn, Lv.74 WAR
Unicorn Harness: DEF: 56 HP+48 Adds "Regen" effect Latent effect: VIT+6
Alumine/Luisant, Lv.45 WAR/PLD/DRK/BST/SAM/NIN
Luisant Haubert (+1): DEF: 40 STR+2 DEX+2 Accuracy+3 Attack+3 Evasion-12
And yes, it is a level 45 version of everyone's favorite Habby... Or at least the +1 is, NQ doesn't have any stats to speak of.
Trader's/Baron's, Lv.20 MNK/WHM/BLM/RDM/THF/DRK/
BRD/RNG/SMN
Unfortunately, this stuff is like the Garish set... No stats, nothing useful, just an excuse for other mages to wear the prized Pimp Hat.
The one you haven't.
Black/Onyx, Lv.71 DRK
Plastron: DEF: 40 STR+8 Attack+16 Damage taken +14% Adds "Refresh" effect
Oh, and if anyone missed it in the lists, they added Lv.55 RSE Earrings.
