From Blind Wolf to Demon Lord! 100x Increase!

 "Finally!" Bob shouted, reaching the light and finding the door as he had before.

 Fear gripped his heart, but Bob did not run. He glanced at the wolf in his hands, who was still fiercely struggling, then at the door, 'I am going to throw you in now little guy.'

 The wolf, revealed in the light to be blue in colour, growled. 

 Somehow, Bob felt if he released this dog like this, then he'd only die a second time. But, as he stood with the door right in front of him, Bob's determination outweighed his fears!

 ⦗Do you wish to level up Level 1 Wolf?⦘

 "Yes!"

 ⦗Level 1 Wolf evolved to Level 25 Wolf King!⦘ 

 ⦗Level 25 Wolf King evolved to Level 50 Wolf Emperor!⦘

 ⦗Level 50 Wolf evolved to Level 100 Demon Lord!⦘

 "What?" Bob watched as the thing in his hands began to grow at an insane pace, and without a second wasted, he ran to the door and opened it throwing the bomb inside, "So not only their level will change, but they'll also evolve?"

 Bob ducked hearing the ear-rending howl, but he did not run! He courageously stepped forward, peaking into the room. There he saw it, a massive blue wolf gleaming with bright runes, dashing with a terrifying speed and attacking the overgrown worm!

 The worm tried to coil around the wolf, but it was a measly Level 10! How could it stand to face a Demon Lord? Before it could achieve its goal, the wolf roared madly and chomped on its head and it uttered a piercing shriek, blood splashing like a fountain.

 ⦗Tundra Wyrm is in Aggressive State!⦘ 

 Bob trembled, watching the blue wolf slap even the enhanced wyrm around like a toy. If not for the wolf being so over levelled, he would have stepped in to steal the kill! 

 Watching the wolf toy with the wyrm, Bob felt dread. If that thing killed him in one hit, then how would he die fighting the wolf? Bob imagined himself getting slapped around to dust and shivered.

 The Demon Lord delivered the final blow, sending the wyrm rolling into the air. As it landed, the once terrifying monster grew still.

 Bob stepped inside the room through the open door, and as the piercing feeling all over his skin weakened, he sighed, "It must be some sort of area effect it had."

 But, let us take our eyes away from the mechanics of gaming effects and on to the wolf who had now turned to Bob. Grinning and baring its fangs, the blind Demon Lord leapt forward, roaring.

 "Thank you for your service, dear pup." Bob sighed, reaching his hand to the wolf, and before it reached him, he used his second developer's hax: 100x Decrease!

 ⦗Level 100 Demon God devolved into Level 50 Wolf Emperor!⦘

 ⦗Level 50 Wolf Emperor devolved into Level 25 Wolf King!⦘

 ⦗Level 25 Wolf King devolved into Level 1 Wolf!⦘ 

 Before the wolf reached Bob, it shrunk a hundredfold, transforming from a fierce wolf lord into a regular wolf dashing right into Bob's hard fist. The wolf was sent flying back until it crashed into a torchlight, whimpering as it slid to the ground.

 "Sigh." Bob stepped over the wolf, walking to the next door. This door was also golden, and with the knowledge he had from earlier, Bob was careful. He pushed the open slightly, peaking inside and finding nothing, 'No monsters in this room?'

 He opened the door fully, then ran back. 

 Nothing attacked him. All he saw was a deep pitch-black darkness.

 "Hmm, what could happen?" Bob rolled his eyes, grabbing a torchlight hung on the walls before stepping into the room. As his light crossed the door, lighting up the insides of the new room, Bob was frozen with fear. Goblins… Goblins as far as the light could reach.

 He turned around to run, but he was too slow. A goblin dropped from the ceiling, cackling with a cold light in its beady eyes as it waved its crooked dagger at Bob before dashing forth, stabbing with the dagger. Bob dodged, swinging his torchlight and attacking the goblin.

 The goblin cried in pain as it staggered back, holding the side of its face and waving its dagger in a frenzy, but the tables had turned. Bob closed in, wresting the dagger from its hands, smashing his fist into its face, then slitting its throat in a fine finisher.

 Bob stared at the dagger in his hands for a while then narrowed his gaze. He bolted as the goblin group chased, leading them into the frozen room as the door slammed shut behind them. Bob stared back at the locked door behind the goblins, "It closed itself on its own?" 

 Well, shucks.

 He spun around to fight. He had no battle experience whatsoever, but it was better than running around with no where else to go! Bob dodged a goblin's blade, stabbing his dagger into the back of its head and splashing blood around as the goblin struggled… to death.

 Panting, he turned to the wolf who had darted off into a corner. 'I could try levelling it up a bit, but there is no telling— nah, it'd probably attack me first.' Bob grabbed his weapon tight, dodging the goblins' attack, sweat dripping down his face.

 A blade slashed at his lower leg, and Bob gritted his teeth, bearing the pain.

 As blood flowed, Bob turned around and slashed at the goblin that attacked him, spilling its blood and sending its head flying into the air, "Dammit. At this rate, I could die again."

 Bob frowned, turning to the hiding wolf, then the grinning goblin mob. He needed to be decisive!
