The consumable appears to be a large backpack. One can put any object inside and loudly declares, while holding the backpack, "If only I had [food item]". Be sure that there are no other items in the backpack, because they will be consumed.
(Note that one cannot request a whole dish; for example, they can order plain macaroni, but not mac and cheese).
Open the backpack after five minutes to reveal the requested food item, whose output weight matches that of the input. The taste of the food will depend on the value of the object. Make sure it's exactly 5 minutes. Who knows what'll happen if it isn't.
On a critical fail, black goo will come out of the backpack, but that’s probably fine because the food looks amazing, right?
On the backpack:
It's easy enough to mistake for any backpack at all, and Delphyrion has not put a label on it. They have lost quite a few beakers and pens to it whenever they mused about their next experiment, as they often reach epiphanies by saying, "If only I had [food item]". Perhaps that's why the artifact works this way.
On food quality:
For some reason the output quality directly ties to the price of food in Orlando. So, put a 5-cent pencil in the backpack, and you'll get a 5-cent quality potato fry*.
Also, yeah, make sure it's 5 minutes exactly. This is a theoretical number; no one has tried to test its limits, hence its reference to Schrodinger.
(On a critical fail, the food appears perfectly made, perhaps too perfect. Ignore the black goo.)
*Food will vanish from your stomach after 2 hours.
On the black goo:
Delphyrion themself isn't sure what it is, nor do they ever remember to analyze it. It doesn't seem to leave any residue on the backpack itself, though it stains quite horribly on porous material including skin. With enough washes it should go away.
If consumed, call the Poison Control Center and pray. Oh hey, is the room spinning?
(Also pray that you are not Dephyrion, the chemist who has had 0 interaction with any religion at all, and therefore still thinks priests can get pregnant.)
On Madness:
One gets uncontrollably angry at the sight or mention of any food that did not come out of the backpack. It feels as if one is running a state-of-the-art restaurant, yet people line up for the nearby McDonald's instead. Delphyrion feels this way towards content farms like 1-minute arts.
Use up this backpack (unless you succeed on 1d10, Difficulty 7) and spend 1 minute. Roll a single D10 as a critical failure check. If you roll a 1, the Effect fails, and you think the backpack has created the intended food item. In fact, it appears and smells more delightful than it should, to the point that you are urged to eat it right away no matter what. You will develop Vertigo upon eating the food as it turns out to be incredibly poisonous. Roll 7 dice Difficulty 6, dice penalties do not apply.
Choose a specific type of Food which could fit inside a regular backpack (up to 27 liters). It must be Non-Alien and generic. You cannot create explosives. You cannot create firearms.

If you succeed, you create a Barrier extending out 15 feet from yourself, which absorbs 2 times the next Outcome + 4 Damage. Only applies to attacks which originated outside the 15 foot radius, and protects anyone who is within that radius. You may choose to create a bubble barrier. If you do, no physical objects or entities can pass into your bubble until the barrier is broken, but you and the barrier cannot move. Half any Damage absorbed by the barrier is reflected back to the attacker. They may attempt to Dodge or Defend using a Desperate Defense, and their Armor applies in full. The Damage reduction from the barrier is applied before Armor. This Artifact may only have 1 active barrier at a time.
You must maintain Concentration while using this Effect. The barrier will fall if you are interrupted, or if it absorbs the full amount of Damage. When a barrier falls, you cannot use this Effect again for a minimum of 2 Rounds.
Remus lay unresponsive on the floor; enshrouded in a cloud of psychoactive gas, his trusty oversized cross laying besides him as always. In spite of his condition, some semblance of a sentence managed to slur its way out of his unconscious lips.
"...Goddamnit, gotta get back to the fuggin' job-"
Still fully unconscious, one hand reached over in a slow and practised movement that had by now reached some sort of muscle memory: hefting up the large cross and slapping himself harshly across the side of the face with the enormous thing.

The Thief casts a container's worth of fine powder into the air. The particulates are drawn to any sort of object that is designed to detect people, including tripwires, security cameras, detection lasers, heat sensors, etc. The powder will not trigger these devices or interfere with their operation, but it does reveal their presence to the Thief.
The cloud drifts and swirls, subtly following the Thief for a minute.

When you detect objects, instead of learning nothing about them, you may observe each object with all of your senses.
The "Reaper" Assault Helmet is the signature piece of the Future Soldier's arsenal. It has a sleek, design and is made of a mysterious matte-metallic alloy. The wearer's face is exposed normally, but when a battle begins, a blue holographic visor flickers to life in front of the eyes. This HUD contains information about the soldier's ammunition and shield status, but more significantly can detect enemy combatants. Anyone nearby who is holding a weapon is painted with a red dot that follows them in real time. This allows the Future Soldier to fire at painted targets in the dark, detect ambushes lurking around corners, and grants an overall tactical advantage.
This Effect activates whenever combat begins. It does not require an Action or Exertion.
You automatically detect all people wielding weapons within 300 feet of you for the next hour. This includes any who come within range during the duration. You have a sense of how many valid targets are nearby, as well as their distance and direction.

Exert your Mind (unless you win a coin flip) and spend 1 minute. This Effect cannot be used unless you drink blood directly from a human until it injures them. Choose a specific Injury on yourself that has not yet been treated with this Effect and roll Brawn + Occult at Difficulty 6.
If you succeed, the Injury is reduced in Severity by your Outcome. If you reduce its Severity to 0, the Injury is fully healed. Otherwise, it is partially healed and will heal the rest of the way at its natural rate.
This counts as a successful Makeshift Stabilization if the Injury was not already Stabilized; any Battle Scars caused by the Injury will remain.
Anyone who witnesses you during this Effect's activation or for its duration will almost certainly be disturbed to see you drink blood directly from the vein.
