Our hero had heard of a potion which would grant him the power he'd been seeking for a while now, the power to protect everyone he loved, to fight back against the forces of darkness which threaten the light of this world.

As he reached for it, he felt a slight... nauseous feeling wash over him. A giddy sense of nervous excitement? Perhaps, but it wouldn't stop him now, he was so close, he'd fought through so much just to get to this moment.

The feeling ebbed away as his beans grasped around the cool glass, sitting amongst the mountain of gold and lifted it from the treasure. He had done it and now.. all that was left was to drink it.

He grabbed the cork at the top and began to tug, wiggling it back and forth until with a loud *POP* it came free, the scent from the bottle was... pleasant, it had that scent of candy mixed in with a powder you would find on a lot of sweet's back in the town, he couldn't believe how this was all turning out, better than he'd hoped for sure.

Lumi took a deep breath and lifted the empty bottle to his lips, his eyes closing as his head tilted back and he gulped started to swallow the liquid, it had a... strange, powdery texture to it, like maybe it hadn't been mixed properly or it was thicker than a liquid should really be, more like... a slime than anything.

The bottle slipped and tumbled from his paws when he was done, landing with a smash as he felt his entire form burn, his frame starting to stiffen in places as he stumbled backwards "U-Ugh... w-what... Is this..." one eye closed as his body shook and shuddered under the power of the spell, his paw glowing as it began to change and shift, less opposable thumbs, more like the paw of any normal animal you might find in the wild "what's... happening..." he panted, another change sending a shiver up his spine as his shaft throbbed and tingled, starting to change and shift from the hanging foreskin covered shaft into a plump sheath snuggly hugging right up against that fat nutsack. His legs came next, causing him to fall onto his rump as they changed, shortening and aligning themselves from the bipedal anthro, thicc thighed boy he was when he entered into the wider frame of a feral.

His eyes wide as he looked himself over, he let out a groan as he felt his power leaving him, all his training, his leveling, it meant nothing... it was gone, his magic, his skills, he couldn't feel any of it. His eyes lingered on the shattered bottle one last time, seeing a label on the base which read "Surpass the trial, obtain what you seek." That was it, the most unhelpful, basic hint he'd ever seen, and he'd been on some seriously stupid quests. He growled inwardly as he looked at himself, the sword discarded at his side, he reached for it, placing his newly formed pawb on the blade, only to be met with a class restriction, it was too heavy for him to even lift.

His ears flickered, a strange... glorp? goopy noise? behind him, causing him to turn around and immediately all the colour left his muzzle, a simple, level 1 slime, something he'd dispatched by stepping on it... but this one... it was huge, or was he just that much smaller? he rolled to grab for the blade desperately this time, but it was no use as the goo surged over him, capturing him in it's tangled mess of slick jelly, he squirmed and struggled, the slime wasted no time in shoving a nice, thick, gooey tendril deep inside of his newly formed feral butt, causing him to cry out as it shoved and shoved and shoved and spread him wider with every passing moment, his health bar taking a hit with every thrust it made into his warm rump, his sheath massaged and rubbed until his new more feral, knotted cock pushed free into the slime, squeezed, rubbed, sucked inside of that warm silky feeling slime and his mouth filled with that... rather delicious tasting bubblegum flavouring that the slim seemed to be made of.

Luckily for our hero, the slime he was swallowing acted as a healing salvent, healing as much as the slime did in damage with every thrust into his warm rump and squirt into his full mouth. His tail maw had suddenly become a lot more active, moving, crying out as time progressed, it couldn't speak, they'd never bonded on that sort of level, not yet anyway. Eventually, the damage of Lumi's new 'sword' thrusting into the slime, finally dispatched the beast, leaving our feral hero covered in slive, full of slime and a little gaping before the dungeon door, which opened, revealing the staircase to level 2...
He stared for a moment, his body aching from the transformation and the abuse... what would he find waiting for him down there? he didn't know... but he had to pass the trial that awaited him so he could obtain his power and his old form once again~
