RWBY: Oscar the gamer

Ding!

[Secret Quest Unlock]

Oscar just Blinked. "Wait what?"

Ding!

[Blood Lust Detected]

Oscar then felt the ground rumbling, as he used [Shadow step] to teleport out the way, as then a Dragon head came out, as Black Fire came out it's mouth, as this was Grimm Dragon, as it looked at Oscar.

Oscar's heart raced as the massive, shadowy form of the Grimm Dragon emerged from the ground, its eyes glowing with an ominous, fiery light. Black flames poured from its gaping maw, twisting in the air with an unnatural ferocity. The very air around Oscar seemed to warp with the oppressive power of the creature. This was no mere Grimm—this was something far more dangerous, something even the dungeon itself seemed to fear.

Ding!

[True Final Boss Detected!]

[Name: The True Black Dragon]

[Warning: The True Black Dragon is an S-rank Boss]

Oscar quickly assessed the situation. The ground beneath his feet was cracked, and the air was thick with the stench of burning sulfur. The Grimm Dragon let out a terrifying roar, sending a shockwave through the dungeon, rattling the walls and making the entire cave system tremble.

Oscar knew he had to be careful. This wasn't like the Kobold Overlord—this was a creature of pure destruction, and it was far more powerful than anything he had faced before. He needed to think fast and plan his moves carefully if he was going to survive this encounter.

Ding!

[Skill "Shadow Step" is now on cooldown for 10 seconds.]

Oscar cursed under his breath. Without Shadow Step, his primary method of evasion, he'd have to rely on his other skills and his wits.

The True Black Dragon reared back its head and fired another blast of black flames in his direction. Oscar barely managed to roll out of the way in time, his body moving with swift precision. He felt the heat from the flames even as he dodged, and the ground where the fire hit melted and cracked. If he had been even a second slower, he would've been roasted alive.

Oscar clenched his fists, feeling the weight of the situation. He wasn't sure how strong this creature was compared to his own abilities, but he wasn't about to back down.

Ding!

[New Skill Available: "Dragon Slayer's Will"]

Oscar's eyes widened at the notification. A new skill? This must've been a special feature for this encounter.

Without wasting any more time, Oscar quickly activated Dragon Slayer's Will, knowing this might give him the edge he needed. A surge of energy coursed through his body, and his vision sharpened, his senses heightening to an almost supernatural level. His connection to the dungeon, to the system, felt stronger than ever.

He raised Midnight Fang, its blade glowing ominously as he prepared for the next attack.

The Grimm Dragon launched itself forward, claws reaching for Oscar with incredible speed. The ground shook beneath its immense weight, and the air around Oscar thickened with the sheer force of the dragon's movements.

Oscar didn't hesitate. He sprinted forward, using his enhanced agility to dodge the dragon's attacks and get in close. With a mighty swing of his sword, he struck at the True Black Dragon's leg, the dark energy of Midnight Fang cutting deep into its hide. The dragon hissed in pain, reeling back, but it didn't seem to be too fazed. This was going to be tougher than Oscar had expected.

Ding!

[Dragon Slayer's Will Activated]

[+15% Damage to Dragon-Type Enemies]

Oscar felt his strength increase even further, the energy of the skill amplifying his attacks. He knew he had a limited time to take advantage of this boost before it wore off, and he wasn't about to waste it.

He moved in quickly, using his Shadow Arms to grab onto the dragon's tail and climb up its massive body. The dragon thrashed wildly, but Oscar held on with surprising strength, his determination unwavering. He reached the dragon's back and slashed with Midnight Fang, landing blow after blow into the dark scales.

Ding!

[Critical Hit!]

Oscar felt the power behind the strike, but the True Black Dragon was still far from defeated. It roared in rage, twisting its body violently in an attempt to shake him off. Oscar's grip tightened, but he knew he couldn't keep this up forever. He needed to end the battle, and fast.

He summoned all his strength and activated Turn Undead once again. The holy light enveloped his sword as he thrust it deep into the dragon's spine. The dragon let out a bone-shaking scream as the light exploded from the wound, causing it to flail and collapse to the ground.

Ding!

[Turn Undead Level 14 → 15]

[Skill Leveled Up!]

Oscar's vision blurred with the rush of power, but he remained focused. He had to finish it now.

The True Black Dragon, badly wounded and struggling to rise, gathered its remaining strength for one final, devastating attack. The black flames in its mouth began to gather once more, swirling with an even greater intensity. It was preparing to unleash a final wave of destruction.

Oscar couldn't allow it. With every ounce of strength he had left, he slammed Midnight Fang down one last time, piercing the dragon's heart with a powerful, decisive strike.

Ding!

[Critical Hit!]

The True Black Dragon has been defeated!

Oscar fell to his knees, his breathing ragged from the intensity of the battle. He looked at the fallen True Black Dragon, its body now disintegrating into shadowy mist. The immense weight of the fight finally settled on him, and he let out a long, slow breath.

Ding!

[Quest Complete: The True Final Boss Defeated]

[+5 Levels]

[You have gained 1x Red Key]

Ding!

[Congratulations! You have unlocked a special bonus for defeating the True Final Boss.]

[Special Item "Dragon Heart" has been added to your inventory.]

Oscar smiled despite his exhaustion. This was it. He had done it. The dungeon was cleared, the True Black Dragon defeated, and new rewards were unlocked. The adventure had been difficult, but it was all worth it in the end.

He stood up slowly, looking around the now-quiet dungeon. There was a sense of finality to it all, but at the same time, he couldn't help but wonder what awaited him next.

Oscar then just stood there. "This um felt a bit easy".

Then blast of as the Dragon flyer up in the sky, he saw it had 3 heads, but one head was dead, aka the one Oscar killed.

Oscar just looked at the Grimm Dragon. "Of course it has second boss mode, active Grimm Human Hybrid transformation".

As Oscar pulled out the Broken Grimm mask from his Inventory, as he put it on

Ding!

[Grimm Human Hybrid transformation Actived Host, this transformation is incomplete. Its power will increase as you level it up. Current enhancements include: Strength +20%, Speed +15%, Regeneration +10%. Be cautious—prolonged use may cause strain on your body. ]

As then a blast of energy came out of Oscar and will this time it didn't heart to transform, he screamed as his body was turned pure black, his clothes fused with his body, as then two wings came out of his back, as his feet was covered by bone like armour, as so did his hands and finger which now had claws, his face has a broken Grimm mask as he has red eyes, a tail came our of his back which had spiked.

Oscar looked the Dragon Grimm. "We both can play this game".

The transformation felt both exhilarating and overwhelming at the same time. Oscar could feel the surge of power coursing through his body as his senses heightened to an almost supernatural level. His movements felt faster, stronger, and more precise. The Grimm Human Hybrid transformation had taken hold of him, and now he was no longer just a human facing the True Black Dragon—he was something else, something far more dangerous.

The air around him shimmered with dark energy as the dragon circled above, its three heads now fully restored and even more menacing than before. The head that had been slain was regenerating at an alarming rate, but Oscar didn't care. He had already dealt with one phase of the fight, and now it was time for the second.

Oscar cracked his neck and clenched his claws, his newly formed black wings flexing slightly. His body was ready, but the real test would be pushing his new transformation to its limits. He knew it wasn't fully developed yet, but the increased power would give him an edge. He didn't plan on wasting it.

The Grimm Dragon roared and dove toward him, its massive form nearly blocking out the sky. Oscar stood his ground, watching the dragon's every movement, his eyes glowing a fierce red under the mask.

With a roar of his own, Oscar took to the air, his wings flapping with powerful beats that sent gusts of wind into the surrounding cavern. The Grimm Dragon was quick, but Oscar was faster. He darted around it with incredible agility, his claws slashing at the air with each pass.

The dragon retaliated with a blast of black fire from its two remaining heads, but Oscar was already moving. He zipped through the air, dodging the flames with ease. Turn Undead was on cooldown, so he couldn't use that to directly counter the attack. But he didn't need it right now. Instead, he used his Shadow Step skill, weaving in and out of the dragon's attacks like a shadow.

Oscar came down hard on the dragon's back, his claws sinking into the thick scales. He heard the creature howl in pain as he slashed down its spine, leaving deep gashes in the wake of his strike. But the dragon wasn't finished yet. It whipped its tail around, attempting to strike Oscar out of the air.

Oscar narrowly avoided it by somersaulting through the air, flipping backward to maintain his balance. He gritted his teeth and narrowed his eyes, focusing. This was it—the final phase of the battle.

The Grimm Dragon flared its wings and let out a piercing roar that echoed through the entire dungeon. It was preparing for a final, devastating attack. Oscar could feel the ground beneath him tremble as the dragon charged its energy, black flames gathering at its mouths.

Oscar immediately understood: it was going to unleash everything it had left in one final, massive blast.

His wings flapped hard again, sending him shooting toward the dragon like a comet. He knew this attack would be powerful, but he wasn't going to let it stop him. He had to end this now before the dragon could use its full power.

As the dragon's three heads aimed their deadly breath at him, Oscar thrust his hand forward, concentrating all of his energy into a single attack.

Grimm's Fury: Shadow Burst!

The air around Oscar crackled with dark energy as a surge of black and purple flames erupted from his hands, combining with the remnants of his Grimm Human Hybrid transformation. The explosion of energy collided with the dragon's fireballs, and for a moment, the two forces clashed in the air, creating a shockwave that sent dust and debris flying in all directions.

Oscar's attack hit its mark, and the dragon's flames faltered. But the dragon wasn't done yet. With a roar, it forced all of its remaining strength into its final blast, pushing the energy toward Oscar with all the might it had left.

But Oscar didn't falter. His wings flapped hard again, pushing him forward despite the intense pressure. With his enhanced speed, he dodged the last of the fire, landing directly on the dragon's head with his claws outstretched.

Ding!

[You have used "Grimm's Fury: Shadow Burst"]

[Critical Hit!]

Oscar sank his claws deep into the dragon's skull. The beast let out a final, anguished roar before its three heads went still, and its massive body collapsed to the ground.

Ding!

[The True Black Dragon has been defeated!]

Oscar stood there, his wings slowly retracting as the energy from his transformation began to fade. He could feel the strain on his body, and the sense of exhaustion began to creep in. But the fight was over.

He'd won.

Ding!

[Quest Complete: The True Final Boss Defeated]

[+10 Levels]

[You have gained 2x Red Keys]

Ding!

[Congratulations! You have unlocked the special item "Dragon's Heart" (Rare).]

Oscar looked down at the True Black Dragon's body, which was already dissolving into dark mist. He could feel the adrenaline still coursing through him, but it was clear that his transformation had taken a lot out of him.

He smiled grimly beneath his broken Grimm mask. "Well, that was... intense."

The dungeon was cleared, the monster defeated. For now, Oscar was victorious. But he knew this was only the beginning. The world was full of challenges, and he'd have to keep pushing forward if he wanted to survive whatever came next.

Oscar then saw something, as he went back to normal, as he saw the Mask was less crack, as he saw the second reword a rio jeans, it seemed to have a dragon degine

Ding!

[ Dragon Scale, when wearing this the Host gets a +5 to speed, Ps: it looks like a Jeans as function as ones]

Oscar puts the pants in his inventory then he remembers the Cleric Beast Skin, which looked like leather jacket with they Cleric Beast degine on the back.

He then opens his Inventory, as he saw the leather jacket

Ding!

[Skin of the Cleric Beast, this increase host speed by +5, Strk +5, stealth+5 while this item is equipped Ps: It just looks like leather jacket and function as once]

Ding!

[Host has collected 2 out of the 6 gear beats armour set]

Oscar just blinked. "Wait what, what do you mean".

Ding!

[This is a special armour set, further information will given to the host when host gets more of the armour set]

Oscar blinked as the system's notification registered in his mind. A special armor set? He hadn't expected this at all. The system didn't often give details unless the set was completed, so it seemed like he was on the right track. Collecting pieces of armor was going to be something new, but the fact that this set had extra perks—and some mysterious aspect to it—piqued his curiosity.

Looking at the leather jacket that resembled the Cleric Beast's Skin, Oscar couldn't help but notice how it felt different from his usual gear. It looked like something simple, but the bonuses were enticing. Plus, there was the matter of the "special armor set."

The bonuses were nice:

Speed +5

Strength +5

Stealth +5

But Oscar had more questions. What would the full set do? What would the remaining pieces be?

"Alright, I guess I'll just have to find out as I go," Oscar said to himself, putting the jacket in his inventory.

He quickly made the mental note that the Dragon Scale Jeans would also be useful, though for now, they would remain in his inventory until he needed them.

Oscar then moved to the exit of the dungeon, heading back to Beacon with a mix of excitement and curiosity about the special armor set and what else this dungeon had to offer. His next objective would be to gather more pieces and see if there were any further upgrades he could achieve from this mysterious set.

With that in mind, Oscar stepped through the portal, his focus now not just on surviving these dungeons, but on collecting the pieces for the Cleric Beast Armor Set and uncovering the hidden secrets within.
