Acquire more magics

Why yes, some magic would be helpful in this situation.

Sophie: "Where the fuck am I gonna get magic out of? Do I just... do jazz hands and yell 'Make the magic happen'?"

Out of spiteful irony, you in fact do jazz hands while saying that exact phrase. And as it happens, the act in question is the secret to unlocking unrivaled magical prowess.

All the lingering, latent magic that was just a moment ago caressing the edges of far-away galaxies and orbiting itself in deep space, now suddenly decides to focus its attention to you. 'She performed the fated jazz-hands', they say, 'let us reward her with our inconceivable power'.

Unrivaled and unchecked power quite literally go to your head in an instant.

Sophie: "W- WH- I feel..."

All power of the vast grandeur of cosmos is siphoned and funneled into you. Lazily wallowing around the vast emptiness, their might is diluted. But condensed into a speckish humanoid figure only a few hundred meters tall, the flurry of power feels decadent and orgasmic.

Sophie: "A-... Ah!"

Your contorted figure writhes itself around, turning half the city into dust and scrap in a few moments of explosive ****. A release of unfathomably immense proportions is building up deep inside you. Something which you are certain will dwarf all of your earlier escapades.

As the density of magic in you intensifies, you suddenly surpass the mass of Earth by the amount of sheer energy. The planet itself starts to turn inside-out in order to orbit you. It feels like each atom in your being pulses with the energy of a supermassive star.

By the simple act of entertaining such thoughts, your form modifies itself to accomodate them. In a few seconds, each of your cells becomes the size of a large star. By this measure, your body in its entirety is now 3 quadrillion kilometers tall, snuffing out in its wake an entire spiral of the Milky Way Galaxy, wiping out hundreds of civilizations at once, without any warning.

At first you see nothing but black, and are visibly confused. But upon moving around for a bit at superluminal speeds and inspecting your surroundings, the reality sets in.

Sophie: "Oh boy. I practically swatted a galaxy flat against my butt. I could've done with destroying stuff more meticulously but..."

Your newly super-enhanced senses can detect the myriads of inhabited and civilized planets still present within the remaining Milky Way.

Sophie: "...I think I might have playthings for a while here."

You get to work. Using this newfound near-omnipotence however, any work to you feels trivially simple. You extract every inhabited solar system from the Milky Way and place them in bottles in an astronomically large display cage.

Then, you begin to wipe out these planets and their civilizations systematically. Setting an arbitrary time limit of 24 Earthen hours, you take delight in discovering new and interesting ways of tormenting and degrading these species with your godlike powers before ending it all by exploding, disintegrating, eating or simply crushing the planets whole. While doing so, you forcibly broadcast this destruction to the next planet in line for them to gawk and panic over.

And after each and every sapient mind has succumbed under your wrath, you move over to the next galaxy. You'll never run out of toys!
