Eddie Drood feats (Property of a Lady Faire)

Eddie, without his armour, smashes a lock open with a statue, shattering the statue in the process:

I finally reached the door at the far end, skidded to a halt, and rattled the handle. It was locked. Of course it was; it was that kind of night. I grabbed a handy piece of heavy marble statuary from its niche (almost certainly centuries old, and valuable beyond price) and used it to smash the lock. The statue came to pieces in my hand, but the door jumped open. I threw the pieces aside and charged through the opening. -Property of a Lady Faire

Torc armour allows the wearer to see in "everything from infrared to ultraviolet", as well as pick up chemical traces on the air:

I studied the waiting room through my golden mask, using the expanded senses it provided, everything from infrared to ultraviolet. But whoever was responsible for all this madness didn’t leave a single clue behind. Everything was still, and quiet. I looked at Molly, and she shook her head quickly.
“I’m not picking up a damned thing,” she said. “No magical workings, no sorcerous radiations . . . Could it have been a bomb?”
“No chemical traces on the air,” I said. “This looks more like . . . brute force. So much blood, but no bodies . . .” -Property of a Lady Faire

Drood armour has the distinct drawback of causing the wearer's emotions to run deeper while it's active:

When I wore the golden armour, I felt stronger, faster, smarter. More alive . . . But it also meant my emotions were bigger, and ran deeper, for good and bad. Right then, I didn’t care. I would do what I would do, and worry about the morality of it later. -Property of a Lady Faire

Eddie catches an RPG rocket fired at him from only a few yards away:

The officer stepped back, and gestured sharply to a nearby soldier, who stepped smartly forward out of the ranks and aimed a rocket launcher directly at me. I started to say something, and he fired the thing at me, at point-blank range. The shell shot across the few yards separating us at incredible speed, the sound of its rocket blast almost overpowering. The sensors in my mask kicked in immediately, speeding up my sight and reflexes till the world and everything in it seemed to be moving in slow motion. I grabbed the shell out of mid-air and cradled it in my arms, hugging it to my chest. It exploded almost immediately, and my armour soaked up every bit of it. There wasn’t even a shock wave to affect the soldiers around me. I’m considerate like that, sometimes. I’d crouched a little, to be sure of smothering the blast, and when I straightened up again, the soldiers made low, shocked sounds as they saw that my armour was entirely unmarked and unaffected. -Property of a Lady Faire

When faced with several "False Knights" capable of taking on Droods in the original armour, Eddie draws his Colt Repeater and, in a moment of ingenuity, surrounds each bullet with strange matter before it's fired. This allows those bullets to punch through the False Knights' armor when they would have simply bounced off otherwise:

The False Knights were almost upon me. I put my hand back through my side, and drew my Colt Repeater from its hidden holster. The gun the Armourer gave me long ago. A very special gun, the Colt Repeater teleported ammo straight into the chambers so it could never run out, and I didn’t even need to aim it exactly. The gun never missed. This was my original idea. My golden blade had pierced the False Knights’ armour, so clearly strange matter trumped bitter yellow. If I surrounded every bullet I fired in golden armour, and punched a hole through their heads as I had with my sword . . . they should fall. I grinned coldly behind my mask, and aimed my Colt Repeater at the nearest Knight.
I shot it through its featureless face. The bitter yellow helm snapped back, and the False Knight crashed to the ground and didn’t move again. The other Knights paused for a moment, as though they couldn’t quite believe what had happened, and then they came on again. I shot them all down, one by one. Aiming and firing as quickly as I could, till my hand ached, picking off target after target. They didn’t even try to defend themselves with different tactics, because they didn’t understand what was happening. They couldn’t understand what was killing them. They’d never seen a gun before. By the time they started to get the idea, I’d already thinned the ranks out so much it didn’t matter. I shot them down without mercy or hesitation, because it was necessary. Not one of them got close to me. I backed away, step by step, still firing as the last of them tried to rush me, until the very last False Knight fell dead at my feet. -Property of a Lady Faire

I don't know how reliable this is:

I stepped up to the Door, and was surprised to find I could still feel primordial cold radiating from the block of ice, even through my armour. It was protecting me, but I could still feel it. I hit the block of ice with my armoured fist, and it just glanced away, without doing the slightest damage. I could punch a hole through a mountain with my armour on, but I hadn’t even cracked this ice. I hit the block again and again, all my armour’s strength behind every blow, and my golden fist just jarred harmlessly against the thick ice. -Property of a Lady Faire

The Merlin Glass Eddie's been using throughout the series? Apparently it has several functions and capabilities that haven't even been tapped into yet:

The Doormouse looked at me carefully. “You’ve been using the Glass as a Door, mostly?”
“Yes,” I said. That much I was sure of.
“The Merlin Glass has a great many other functions and capabilities built into it,” said the Doormouse. “Some of which have apparently never been accessed, never mind activated. This is a very intricate piece of work . . . I looked inside it, and it just seemed to fall away forever . . . There are layers upon layers, levels within levels. Merlin always was ahead of his Time. I can’t even say for sure what the original purpose of the Glass was. What he intended it to do for the Droods. Or to them . . .” -Property of a Lady Faire

Eddie can throw punches powerful enough to demolish a house. Clearly not hyperbole given some of his other feats.

I kept hitting them, and they kept getting up again. I hit them with punches that would have demolished a house, but the damage just wouldn’t take. -Property of a Lady Faire

Eddie's torc can slow down his perception of the passage of time:

I still had my armour in place under my white security mask, and I used the strange matter covering my eyes to slow down the passing of Time, so I could follow the teleporting more easily. Slowed right down, a pattern in the jumps quickly became obvious, and it was easy enough for me to figure out where Jumping Jack was going to appear next. He was following a familiar, well-rehearsed pattern, not nearly as random as it seemed. So I just needed to position myself carefully for his next appearance. -Property of a Lady Faire

Eddie's torc protects him from the Lady Faire's influence:

She stood up abruptly, and advanced on me. I stood up to face her, and didn’t retreat. She strode right up to me, and I put up a hand to stop her. She took my hand in both of hers and clutched it tightly. Her hands felt very soft, and very warm, and very strong. She was standing close to me now, only our linked hands separating our two bodies. I could feel the breath from her mouth on mine. Feel the forceful pressure of her breath on my lips. Her eyes stared into mine. She hit me with the full force of her influence, and whether it was the pheromones or her personality, it didn’t matter. I could feel my willpower withering, like a moth in a flame. And there, in that moment, I wanted her like I’d never wanted anything else in my life. But I’d had a lot of experience in wanting things I knew I could never have.
So I did what I always do when I feel threatened. I called up my armour, and it flowed out of the torc at my throat and covered me from head to toe in a moment. Sealing me off from the world, and all the things in it that were a danger to me. The golden strange matter closed over my hand, gently forcing her hands away. And just like that, her power over me was gone. Swept away like a bad dream. She could tell. She stayed where she was, looking at her own face reflected in the featureless golden mask. -Property of a Lady Faire

(As a note, this was the same influence that was able to affect the entire Ballroom of the Winter Palace, which had [among others] Dead Boy. The same Dead Boy who resisted a psychic attack from the Primal)

Eddie crushes the Lazarus Stone(?!) with his armoured hand:

She gave me the Lazarus Stone, placing it carefully on my outstretched hand. It was very heavy for such a small thing. Heavy with the weight of potential responsibilities, perhaps. I held the Lazarus Stone for a long moment, and then I armoured up my hand and crushed the Stone to dust. It didn’t try to resist. I opened my golden glove and let the dust fall away, into the deep dark waters of the pool. It vanished in a moment, leaving no trace of its passing. -Property of a Lady Faire
