Give the Wishing Pendant a test.

I focus on the pendant for a long time, studying it while I keep moving it between my borrowed fingers. I'm trying to see if this magical artifact has any physical feature that can give away any clue to its incredible powers. But no matter how long I stare at it, it still looks as lame and cheap as the first time I saw it. Just a piece of broken pink quartz attached to a steel chain.

Who would've thought that this ugly trinket, which looks like it was bought in a Chinese bazaar 30 years ago for 2$, was a magical artifact capable of granting wishes?
Was this the reason my mother always wore it for so long...? No, that can't be. If my mother really knew the true nature of this pendant, I'm sure she would've used it on our benefit. There is no way that she wouldn't have lived a different life had she known any better. But instead, she lived her latest years like a drunk and died prematurely because of that.

I don't feel sad anymore when I think about my deceased mother. That wound has already been fully closed. But I still give myself a few moments of silence out of respect for her memory.

[...]

At the end, I decide to give the pendant a test.

"Hmmm... What wish should I make...?" I ask myself, feeling a little insecure.

But then I look down at the old t-shirt I'm wearing right now that I used to wear on my original obese body, but that it's several sizes too big for Devon's thin physique. Seeing it hanging down over his black skin like some kind of loose circus canvas oddly reminds me of that awful style some idiots used to sport in the late nineties.

"I wish that this t-shirt fits me." I say loud and clear. And the next second, the quartz pendant starts glowing with purple light.

"Woah!" I exclaim in surprise when I feel all that loose cloth retracting over my borrowed body, reducing in size until it fits Devon's torso like a glove: not too tight but not too loose either.

I can't help but smile like crazy. This is amazing! Only now I'm finally realizing the potential of this artifact my mother left me. I can feel Devon's heart bumping in his chest responding to my own excitement. Oh god, what should I wish for next? Maybe I could get a little more ambitious... right? Nothing too crazy though.

"...Pendant..." I start while pointing at the table. "I wish to have 1.000.000$ appearing over my kitchen table."

I inhale strongly in preparation for when that fortune materializes in front of me. But after a few seconds, I notice that there is no reaction from the pendant.

"...Huh? Nothing happened?" I say, not understanding what went wrong.

So I try reformulating the wish, again and again, with different words and timings. But with no result whatsoever.
I'm starting to get nervous.

"Pendant. I wish to know why you didn't grant my last wish!" I exclaim.

But this time, the pendant obeys my command and glows with its soothing light. And the next instant, a stream of information appears into my mind.

[THE OWNER'S LAST WISH COULDN'T BE GRANTED DUE TO ITS MANA REQUIREMENT SURPASSING THE CURRENT MANA RESERVES]

"Uh, w-what the...? Mana requirement? r-reserves? What is that? Uhm... I, uh... I wish to know what is that!"

[MANA REQUIREMENTS REFER TO THE QUANTITY OF RAW MANA NEEDED TO SPEND IN ORDER TO GRANT EVERY INDIVIDUAL WISH, WITH EACH WISH HAVING A VARYING LEVEL OF REQUIREMENT DEPENDING ON THEIR COMPLEXITY AND POWER NEEDED]

[WHILE MANA RESERVES REFER TO THE RAW MANA CURRENTLY STORED INSIDE THIS ARTIFACT]

"I-I see..."

So... If I understood correctly, this pendant has some kind of... magical battery. And every wish consumes power from that battery.
But if the pendant denied my last request, doesn't that mean that the actual battery is very low...?

The sudden realization stops me in place. And I look down at the pendant with a layer of cold sweat slowly forming over my forehead. I really do not like the implications of this artifact having a low battery. What will happen if I can't have any more wishes? What will I do when the authorities finally discover my(Mark's) disappearance? And what about my future? I don't wanna be stuck inside this black dude's body!

After a brief moment where I almost panic, I manage to calm myself down and think carefully of my next movement.
If this pendant has low battery, but I can still ask it to give me information, that means that such wishes have a very low cost in mana or whatever. But I still need a lot of info, so I make a risky decision:

I get up and go to my room, where my phone is charging. Then I turn it on.

"Pendant..." I say with a trembling voice. "I wish to have an App on my phone that displays all the information I might need from you, including your mana reserves, the cost of every wish I make, how do I recharge you, etcetera..."

With yet another purple light, the pendant grants me my wish. And after a quick search through my phone, I notice that a new icon has appeared right on the last page. It is a simple white background with the purple pendant plastered over it.

"This has to be it!" I say, extremely nervous.

The moment I click the image, My screen becomes completely purple and I see a display menu over the top-left with 3 options, all in yellow letters:

-Characteristics of the Wishing Pendant
-Mana Reserves and other details
-Further instructions and recommendations

I immediately tap on the second option and I see this:

It looks like a summary of the current battery level and how much did every one of my wishes cost to be granted.

"Fuck! So this means that the pendant only has 5% of battery left?! But then, how do I..." I start scrolling down frenetically. "Ah! here it is!"

Right at the bottom of the screen, I see 2 more measures.

Mana absorbtion from current environment: 0.5%/24h
Mana absorbtion if this artifact is in physical contact with a human body: 17%/24h

"I see!" I exclaim. I finally understood how to recharge this pendant.
...Or I think I did.

So, to summarize: this artifact recharges 0.5% every day if it gets left by itself. But if I'm wearing it, it will recharge 17% instead!

I allow myself to fall over the bed, sighing in relief. Man, I was scared for a moment. I don't know what I'd do if this pendant needed some kind of complicated magic shit to recharge, or if it told me that it needed a year to recharge 1% or something like that.

But wait...

I look at the phone once again.
It says that my first wish, the one I used to possess Devon's body, it cost me as much as 40%!
And since I have 5% remaining, and it will be recharging 17% every day as long as I'm wearing it, that just means...

That I'm trapped inside this gross body for (at least) 2 more days!

I cover my new face with my borrowed hands.

"Ffffuuuuuuuuuuuccckkkk..."
