Hell yes, got a Cursed Bite from a chest in the room with Living Armor. And to boot it's based on my favorite sword design in the game (Carnation).
My story for the night (with a protip at the end). I'm at 70 in part three of BBI, still rolling my solo sword Assassin. Fight my way through the Spectres with my trusty Throwblasts, kill an Elder Ogre to complete the quest. After running into Death and pulling a ninja on out of there, I get to the room with Living Armor.
A big buffed MK, joy. I go at him and find that he has my favorite trick...dude spams Full Moon Slash. FML. Using a Surging Light Tome (Holy Furor) to stagger him, I start shredding him with four Conqueror's Periapts and Full Moon Slash, using Clairvoyance to stuff his shield counters. Everything is going good...then his armor comes off. Oh hell.
Now he's like a spectre, immune to physical attacks and only magic dents him. I'm a solo Assassin. This is bad. I use my magic tomes and Jewels of Summoning to whittle away at him and he nails me with a big hit. I'm low on heals and magic items, so I back off while I think of how I'm gonna win this. He's quick and gives chase so I climb up the steps to the top and jump out on the pillars where they normally put chests (there's a Macabre Sculpture up here, FYI guys), thinking he can't get me up there. Turns out, he can. The armor jumps up on the pillar and goes to charge me, I'm waiting for the attack to use Clairvoyance...and he falls off and hits the ground. And dies. XD
So, that protip I mentioned (besides always carry magic tomes if you're solo)?
Living Armor will insta-kill himself if you climb up the stairs and jump on the pillars, and let him chase you.
I drop down, take his loot, raid his chests and get my sword. A good day of adventuring.
