Redo: Grimoire System in the Apocalypse

Geth awoke to the bright rays of the sun gleaming across the treetops. He stood and stretched while patting down his ruffled beard from a good night's sleep.

After casting Mass Invocation again, he sprinted the final stretch between himself and the Dungeon. The sun had barely made it over the distant tree line as he stared down into an open pit.

He looked around. There was nothing but flat land in almost every direction.

'I remember this being farmland before.' Geth thought back to when he'd spent the summer working in a nearby field.

Very few Skeletons wandered around nearby, twenty at most. Geth remembered that their cores were used to make Agility potions, which would be essential for travel in the future. 

As such, he didn't plan to let a single one slip by. These creatures were different from the Zombies.

Where the Zombies had no Mana, these Skeletons seemed to be held together by it. A weak aura similar to his Corruption Aura Skill held their bones together.

A light green core floated inside of each creature's rib cage. Most of their Levels were in the range of 35-38.

'They are higher Levels than I expected. Maybe I'll find some over Level 40 deeper in.' 

He ran around the clearing, getting the attention of the wandering Skeletons. When they surrounded him, he stood and waited for the one closest to him to swing its sword.

The blade's sharp edge struck his right shoulder and simply bounced off. After that weak strike, Geth couldn't help but let a smug grin show on his face.

He cast Mass Invocation, causing 2680 damage to the surrounding Skeletons. After casting it a second time, the bones turned to dust, leaving nothing but the green cores lying on the ground.

'These creatures are incredibly frail. Agility and Intelligence must be their only assets.'

He gathered the cores and weapons into one of his storage items. The items were surprisingly high quality, all being Uncommon.

Geth then ventured down the spiraling stairs, disappearing into the darkness of the chasm.

He didn't have too much trouble seeing in the dim hallway with inspection active. A dim light shone from gems that were embedded in the walls.

The place was built from stone instead of being a natural structure. Geth ran his hand along one of the walls as he proceeded.

After traveling just over a hundred feet, his hand slipped into an opening that he probably would have missed. It was a rectangle opening in the wall the size of a small doorway.

He looked forward down the hallway and could tell that there was still quite some distance to cover. Geth stepped through the doorway and found himself in a massive circular room with a chest in the center.

The room was exceptionally dark compared to the hallway. The only light source was a stand on either side of the chest with eerie blue flames glowing.

He looked around and found that hundreds of Skeletons lined the walls. A single giant Skeleton stood against the far wall behind the chest.

'Someone with poor vision would have only seen the chest and nothing else,' Geth thought. 'What a blatantly obvious trap for a Dungeon.'

He still shrugged and proceeded into the room. It wasn't like a bunch of Skeletons could hurt him.

There was also the off chance that the chest had something decent in it. Plus, he wasn't one to let free experience slip by him.

He sauntered into the center of the room, watching the Skeletons and waiting for them to make a move. They still hadn't budged by the time he was standing before the ornately decorated chest.

Geth peered into the darkness at the largest Skeleton of the group. It was around nine feet tall, boasting thick armor and a sizeable double-bladed ax. 

:Skeleton Knight, Lvl 41 (Sub-Boss); HP- 29,500/29,500:

'Its health is so low.' He glanced around at all of the normal Skeletons as well.

:Skeleton Guard, Lvl 40; HP- 5200/5200

Skeleton Raider, Lvl 39; HP- 3600/3600

Skeleton Archer, Lvl 40; HP 2650/2650:

'These things are all incredibly fragile. It's no wonder Blaze and Swole had no issues with soloing these Dungeons.'

'The two of them also have their own unique sets of abilities that make it easier for them to fight against a crowd,' Albus added.

Geth reached down to grab the chests clasp while listening to Albus speak. The instant his fingers brushed against the chest, multiple braziers around the room lit up.

The sudden light almost blinded him. At the same time, the Skeletons around the room began to close in.

He stood and waited for them to come closer, casting a Barrier between himself and the area with the most Skeleton Archers.

He judged that he could cover about half of the room with the current size of his Mass Invocation circle. 

He didn't forget to remind himself that if he'd gone with Universal Blessing, he could probably clear this entire Dungeon while standing at the entrance.

The Skeletons swiftly made it into his Skill's range. They did have high Agility, after all.

He cast Mass Invocation twice and instantly wiped out all the small fry. The Skeleton Knight was weakened but kept pushing forward.

By the time the monster took its first swing, Geth had cast his Skill for the tenth time and watched the behemoth turn to dust before him.

The enormous ax fell onto the ground, the sound of metal echoing throughout the room and down the hall. He shook his head as he looked at the size of the thing.

'I really need to start picking up more storage items.'

He then flipped the chest open and found a single item inside. Geth reached into the deep chest and stood back up with a blank card.
