DUNGEON CREATOR

Prologue.

“SHIT!”

Shouted the middle aged swordsman who keept failing to land a clean hit on his opponent. It had been several minutes but there was no sign of the fighting coming to an end.

With a sword in his right hand, and a shield in his left hand. He tried repeatedly attacking his opponent, every single one of his strikes was blocked by his opponent's shield. Despite his wastefull efforts, he keep pounding his sword against his enemy's shield. He had hoped that he could keep his opponent busy while his comrades fought almost the same thing as the he did.

“What’s with these guys?”

Complained a red robed mage as he launched a ‘Fireball’. No matter how many times he cast his spell, or how many variant offensive spells he cast, the enemy always manage to neutralize it with the same spell as the one he cast. When the two fireball's clashed together, the area grew uncomfortably hot.

“Damn it! Can you at least pick a spell that's not going to roast us?”. The parties theif complained.

“I've almost run out of mana here, so I'm forced to use just the low cost basic spells”. The mage replied.

For a while now, this party of four had become desperate and nervous, so the thief said jokingly while grinning in attempt to ease their tension a bit.

“Well at least try to use some ice magic or something”.

Both swordsman bantered back and forth as well. One is the middle aged man with the sword and shield, the other is a woman in her 20's with a long two-handed sword as her weapon.

“But still It’s weird to be fighting with yourself and still be losing”, the female warrior said.

 “Yeah, but these guys don’t seem to be tireing at all”.

The mage joined in their conversation while blocking his enemy spell.

 “And it seems like these guys don’t use mana at all”.

“I mean, my opponent just keeps firing spells like they cost him nothing”.

By no means was this party of four weak, one would even say they are above your average adventuring party. While an ordinary group would panic when they are facing their own reflection as an opponent, this party remained somewhat calm despite their dire situation. Their opponents looked almost exactly like them, the only difference is the enemy's expressionlessnes and an odd greyish tone to their body.

While the fighting grew even more fierce, fatigue started showing on those four. They realised they couldn't win this fight. Facing back to back with each other they’d been surrounded by the four human-like monsters who replicated them.

“How did we end up like this?”

The thief was regretting his own greed. Earlier they were wandering on the 10th floor of newly found dungeon. It had now become a safe zone because the boss guarding room had been defeated. Every time a dungeon boss is killed, somehow they never respawn and. It is apprently some dungeon rule or something, thus the humans make their safe zones in the former boss rooms. Boss rooms are a large emyty space consisting of just the treasure chest, the boss monster, and its subordinates. After the boss is defeated the subordinates usually just disappear without a trace and leave the treasure it's guarding behind. While wandering aimlessly they had overheard some people in the corner talking about a crevice on the 9th floor.

“−Told you there must be some treasure there”.

“But that’s an unknown path, and not to mention the danger. Besides, we don’t know where the crevice leads to”.

“But its only on the 9th floor, the danger can't be that bad”.

“That’s enough. We came here to train our newly recruited members, not to go treasure hunting”.

“Tch, alright then”.

Their original goal for entering this dungeon was to find some treasure, but for some unforeseen circumstances they were delayed. Being late coming here, now all the boss treasures up to floor 30 had already been taken. While there’s still floor 40 and on, they decided to find the crevice for some slight hope of treasure. After finding it on the 9th floor they went to prepare and restock thier food supplies in the safe zone. After a day of prepairing, they went trough the crevice only to find themselves in the current situation.

“Tch, weak”.

While looking trough a mirror-like item, the dungeon master muttered as he stared at the four C rank adventurer corpse's lying on the dungeon floor. After some time had passed,  a greyish mist surrounded the corpses, animating them. Instead of fading away, the corpses stand and begin walking away.

“They only lasted 15 minutes against their doppelgangers, disappointing”.
