First up were extra precautions, and I had the perfect items in mind.
I was glad I included all those safeguards in the form. In the world I've found myself in, it wouldn't be strange to die from a sudden "gas leak" or a random magus who wanted to use you for an experiment.
I reached into the Inventory and pulled out something unassuming, a goblet overflowing with glowing pink water.
-o-
Fountain of Youth (The Seven Deadly Sins)
The Fountain of Youth, a sacred treasure of the Fairy Clan. Licking its water will grant ten years of extra life, swallowing a sip of the water will grant a hundred years, and drinking it all will grant eternal life and immortality. As long as it's water is not drunk completely, the liquid will replenish itself over time, but should all of it be consumed, whoever consumed it will become the Fountain of Youth.
Fully consumed, it grants you Eternal Youth and Immortality. Gain an incredible healing factor allowing you to recover from anything as long as your soul is not completely destroyed. In addition, the Fountain's healing and youth restoring properties are transferred to your blood.

I simply stared at the goblet for a moment before swallowing the nervousness that was crawling under my skin.
"Immortality in the palm of my hand."
Part of me still couldn't believe this was all real. If this really was a dream, I would probably be a bit depressed if I woke up, so I should squeeze out as much as I could from this experience.
"Bottoms up!"
The cold metal of the goblet touched my lips as I drank its contents. It tasted like a warm blend of watermelon and lime—sweet, but also sour and acidic, with a distinct zesty and bitter aftertaste that somehow worked.
As soon as I drank the last drop, it felt like my entire body was dipped in the most relaxing sauna, a gentle warmth seeping into every bone and muscle. My skin tightened subtly, a fresh vitality humming beneath the surface, as if every cell had been given a five-star spa treatment.
A satisfied sigh left my lips. "Tastes like the best fruit juice in the world."
From now on, even if I was reduced to ashes, I would still regenerate back to full health. Perhaps not even Wolverine's regenerative ability would hold a candle to mine.
But that still wasn't enough for me.
I held out my open hand once more. A luxurious piece of equipment made of gold and decorated with blue enamel that seemed more like a treasure to show dignity and nobility materialized in my grasp. It radiated a soft, brilliant glow of gold.
My eyes widened in amazement, mesmerized. Never in my life had I seen such a beautiful piece of art.
-o-
Avalon (Type-Moon)
The hallowed Scabbard of Excalibur, created by fairies alongside it. The embodiment of Utopia. Its connection to the heart of the world, Avalon, grants its wielder regenerative immortality simply by carrying it.
When Mystical Energy is supplied and its true name is called, it becomes the ultimate shield, by overwriting the rules of the world around you temporarily to become like the utopia it is connected to, a world where the concept of harm and hurt does not exist.
It is on the level of true magic and is an actual true magic in itself that transcends all magecraft. Not even the Five Magics can overcome the barrier.
-o-
Putting it against my chest, I watched as it sank into my body like it was sinking into glowing golden water. If I concentrated and closed my eyes, I could sense the sheath resting inside me, waiting for me to call upon it.
Something inside me stirred as soon as I made Avalon a part of myself. The Celestial Inventory instantly presented a prompt: Elemental Affinity and Origin change to 'Sword'?
My brow furrowed. For a native magus of this world, that would mean extreme specialization, a narrow path, and a lot of headaches. But I wasn't a magus, and with literally infinite options when it came to power acquisition, why limit myself? I mentally dismissed the prompt. No thanks, I'll keep my versatility.
Avalon's regenerative power would synergize with what I got from the Fountain of Youth, enhancing my regenerative ability, but the main reason why I summoned it was because of its ability to shield me from anything. Not even the King of Heroes' Ea, a weapon that surpassed all and was capable of unimaginable destruction, would be able to harm me.
"My defense is done. Now for offense."
I closed my eyes, holding my chin as I went into deep thought.
In truth, I could roll out as I already was. Celestial Inventory essentially made me a better Gilgamesh, and I could use it like he would—an endless barrage of Noble Phantasms, shot from portals as if they were artillery. But that approach was too straightforward for me. What was the point of having every "item" from every universe if I didn't use them?
The only issue for me was that there were truly too many options to choose from. It was slightly overwhelming. Still, if I were to fight fire with fire… Maybe this one?
This time, a helmet appeared in my hands.
It was elegant, ominous, divine, gleaming like polished gold, smooth and sharp, catching the light like a molten sun. Carved holes rested where eyes would see through.
Holding it made the world feel quieter, like even the wind held its breath. And when I moved, it pulsed, like gold light dancing across the metal.

Helmet of Fate (DC Comics)
A premiere magical repository created by the Lord of Order Nabu to contain his essence, The Amulet of Anubis, and the Cloak of Destiny, which are woven with all sorts of anti-magical protections.
The Helmet itself bestows a number of abilities, acting as a wellspring of intense magical energy, capable of channeling directly from the realm the Lords of Order call home. To this extent, it allows the user to shape and command magical energy in ways that would leave all but the most adept of mortal sorcerers baffled, creating constructs, enchantments and mystical effects beyond the pale of most. Such is its command that it can even weave other esoteric sources of power through it, though this requires skill and focus. Similarly, this Maelstrom of power gives the user resistance from most magical effects, and outright guards them from probability manipulations and precognitive effects.
It also naturally gives the wearer great magical sight and awareness, allowing them to see all magical effects, sympathetic links, and spiritual movements within the area, and what caused them.
Finally, the Helmet's most unique effect is the spirit residing inside it that grants it its connection—Nabu. With Nabu residing in the helmet, it heightens its imaginative casting, making it far easier to use for the inexperienced but talented and creative who often found themselves his hosts.
It is worth noting of the Helmet that while its inhabitant will probably be cooperative, they have their own personalities, goals and motives to consider. Nabu specifically has been known to attempt to rend control from his hosts in extreme situations.

Actually… now that I thought about it more, maybe it would be best to leave this for difficult problems or worst-case scenarios. This was the kind of thing I should only bring out if absolutely necessary, to take care of an inconvenience really quick, or to completely wreck someone's day. If I wanted to, Doctor Fate's powers could even let me affect entire universes across the multiverse.
But the sheer potential radiating from the golden helm was intoxicating. Curiosity, that old, dangerous companion of mine, prickled at me.
"Just a peek," I murmured, the words barely disturbing the heavy air. "Just to know what I've got in reserve."
Slowly, almost reverently, I lifted the Helmet of Fate towards my head. The polished gold felt unnaturally warm, humming with contained power. As the cool metal settled against my temples—
The world exploded.
Not in fire or sound, but in understanding, the Celestial Inventory granting me perfect mastery and knowledge of the artifact in an instant.
Nabu's consciousness brushed mine—ancient, vast, impossibly orderly, like a cosmic librarian who had cataloged the fundamental laws of existence. The CI's bond was absolute; the Lord of Order was present, cooperative, yet fundamentally subdued. His immense power was mine to command and the knowledge flooding my mind was crystal clear.
This power was a sledgehammer designed for multiversal anvils. Using it carelessly here would be like cracking a walnut with a supernova.
Simultaneously, a wave of pure, structured power surged, and a profound physical transformation swept over me. Nabu's divine empowerment.
I felt my physical form instantly optimized to its absolute peak. Strength, stamina, reflexes honed to perfection.
My entire body was now encased in a sleek, blue bodysuit with golden armor layered on top, reminiscent of an Egyptian pharaoh god. In the center of my chest, an intricate, glowing Ankh symbol laid bare. A heavy, segmented golden cape materialized at my shoulders, flowing with unseen energy as if woven from starlight and cosmic wind. My eyes blazed with pure, piercing light from within the helmet's eye slits, casting an otherworldly glow.
I was Order incarnate. A divine, golden sentinel radiating ancient power.
Elemental Control, Eldritch Blasts, Construct Creation, Teleportation, Telekinesis—all of Nelson's personal magic and more—thrummed at my fingertips, instinctive and boundless. Immortality and near-invulnerability layered onto my existing defenses like cosmic plate armor.
Then came the Sight.
Fuyuki City vanished, replaced by a living tapestry of magic I comprehended utterly. Ley lines pulsed like neon-blue rivers beneath the streets. Their convergence points, their strength, and their vulnerabilities were laid bare. Wards on distant buildings glowed like intricate spiderwebs, their purpose, age, and weaknesses instantly known.
The faint signature of a complex bounded field? Rin Tohsaka's work. The more complex, wider bounded field in the Einzbern forest? Its origin and current state were revealed to me like highlighted words on paper.
Beyond the city and beyond the world were threads of possibility, shimmering pathways connecting countless realities flickered at the edge of my perception. I translated the scale instantly: infinite potential, anchored by Order. Power, raw and elemental, drawn from its dimension, thrummed in my veins, its precise mechanisms and limits known to me as if I'd wielded it for eons. Probability felt malleable. Precognition a fog easily dispersed. I knew, absolutely, what I could do with it.
It was power on a multiversal scale. And wielding it here, now, was... overkill. Like bringing a particle cannon to a fist-fight. And what fun would that be? I wasn't here to end the game before it even started.
With a thought, I willed the transformation undone. The suit and golden armor dissolved into light, the heavy cape vanished like smoke, the light in my eyes extinguished. The Helmet was lifted cleanly from my head, as if held by invisible hands.
The mundane sounds of Fuyuki rushed back. The vibrant tapestry faded. My heart hammered, not from fear, but from the exhilarating clarity of what I'd just experienced and knew I held.
Then something deeper registered. It was a subtle shift within my connection to the artifacts themselves, confirmed instantly by the Celestial Inventory's knowledge. This brief union hadn't only granted power while wearing the Helmet. It had forged an instant, permanent connection to the fundamental powers of the entire Trinity—the Helm, the Cloak, the Amulet.
The potential was staggering. Trace elements of Nabu's divine empowerment strengthened my muscles and sharpened my mind, slivers of immortality reinforced my Fountain/Avalon defenses, whispers of Nabu's arcane knowledge danced at the edge of my thoughts, and the potential to cast potent magic hummed beneath the surface.
These were echoes of the power held by the artifacts of Doctor Fate, accessible without summoning them.
"Now that's efficiency," I chuckled, my smile turning predatory. "One peek, and I get the full package plus passive dividends. A permanent magical upgrade. The Artifacts and the Helmet's connection to the Lords of Order's realm are mine, worn or not. Definitely saving this for when someone needs their entire existence retroactively rewritten. Or maybe just for when I feel like fighting cosmic gods for funsies."
Profound satisfaction settled over me, deep and warm. Storing the Helmet wasn't simply locking away power. It was sheathing a universe-shattering blade, knowing its cosmic signature now hummed within my bones, a permanent, silent augmentation to my existence.
Discrete was definitely the way to start, though, so instead of the Helmet of Fate, this time, I urged the Inventory to give me something more discrete.
Something powerful and unassuming that would allow me to wield a versatile form of magic.
My power complied with my wish. A wooden ring manifested around my right hand's middle finger, possessing a smooth, unadorned surface.

The Elder Ring (Harry Potter Alternate Universe)
The Elder Ring is one of the three Deathly Hallows. This ring will give its loyalty to whoever could win it from its previous master. When worn, it significantly amplifies any magic casted. You can make charms and transfigurations permanent, and charms become more potent.
The Elder Ring can twist your magic in any way you need, reducing or eliminating the need for ingredients. Any magic that normally requires lifeforce now doesn't and normal limitations of spells can be overcome with brute force. Repair things that are too broken for any Reparo, heal wounds caused by the Dark Arts, negate any curse with Finite, and so on.
In a duel, you will almost always emerge victorious against someone weaker than you, but you will be challenged when it comes to someone of equal or greater strength.
-o-
"Woah…"
I blinked at the sudden influx of magic, knowledge, and experience. Its was a sudden clarity and felt like this ring was something I wore for centuries as I honed my magic.
It was the exactly the kind of artifact I wanted. If the Helmet of Fate was a sledgehammer, then the Elder Ring was a scalpel and a swiss army knife all in one.
Harry Potter magic was incredibly versatile on its own, capable of doing nearly anything you could imagine as long as you had the knowledge and skill required. Using it, I could transfigure people into animals and make inanimate objects move like they were alive, render myself invisible using an Invisibility Charm, teleport to places thousands of kilometers away, and more.
While wearing the ring, I was a wizard more powerful, knowledgeable, and talented than Dumbledore, Grindelwald, and Voldemort combined. And in this world specifically, no magus would be able to match my diverse and extensive repertoire of spells.
I wanted to test it out immediately. Looking down, I spotted a cracked cinderblock half-buried in the rooftop debris. Perfect.
I pointed my ring-clad finger at it.
Reparo. (Mending Charm)
Magic surged—clean, precise, and utterly effortless. The Elder Ring's amplification wrapped around the spell like a velvet glove. The cinderblock didn't simply reassemble; it flowed back into wholeness, fractures sealing like liquid stone until it sat pristine, as if freshly molded.
"Huh. Neat."
Next, I focused on a twisted rebar rod jutting from the concrete.
Evanesco. (Vanishing Charm)
I saw it disappear, but I knew it didn't merely vanish. It went into non-being, which was to say, everything, leaving empty air in its place. It didn't leave any residue. It was just… gone.
"You're a wizard, Kayden," I said to myself, grinning like a cat.
A birdcall then drew my attention to the right, where a brown bird stood on the ground. Its beady eyes peered into my own. An idea came to mind.
But should I? Hmm.
Fuck it.
In a slow and calm manner, I raised my hand, aiming it at the bird.
"Avada—!"
As if sensing its impending doom, the bird flew flapped its wings in a desperate escape.
I narrowed my eyes at the fleeing avian. Restraining it with a spell would only take a wave of my hand, but I held myself back. It wasn't worth the trouble.
There were better targets for the Killing Curse.
I brought my attention back to my magic. The synergy between the Ring and the connection I had with the artifacts of Fate were already singing. Nabu's passive hum of cosmic Order blended with the Ring's hefty amplification. I felt the low thrum in my veins, waiting to twist any spell into something more.
Permanent transfiguration? Healing debilitating injuries? Barriers that laughed at conceptual curses? All possible. All easy.
The magic I wielded was vandalism against this world's rulebook.
And I hadn't even touched the Class Cards yet.
