Redo: Grimoire System in the Apocalypse

Geth glanced over to ensure that the loot was stored before grabbing the Crystal. The moment he touched it, words could be heard in the minds of all those present.

"Congratulations, User, for clearing a Team Dungeon. Please select a reward. Options available will be based on performance."

Words began to appear on Albus\' pages.

:Congratulations, User, for clearing a Team Dungeon. Please select a reward.

Note User had the highest contribution. Options adjusted to match feats.

Option 1: 6 TP, 6 SP, Random Epic item

Option 2: 12 TP, 12 SP, 12 AP:

"Option 2." It was a quick response. However, if Geth had been offered an Epic Item suitable for his Class, he might have chosen differently. 

:Dungeon Crystal (Level 0) Experience 0/10,000

Can be upgraded using Monster Cores.

Owner- Geth

Owner is already in possession of a higher Level Dungeon Crystal. Would you like to subordinate the current Dungeon to Level 2 Dungeon, Valhalla? Yes / No:

"Yes."

:Congratulations on obtaining subordinate Dungeon. Subordinate Dungeons are directly leveled in conjunction with the primary Dungeon, Valhalla. As this is an open Dungeon, there are only two Locations offered.

Location 1: Wall

Location 2: Barracks

Note: This is User\'s first open Dungeon. Open Dungeons can be built in by those with a Craftsman Class when accessing the Dungeon Crystal.

Owner can choose to accept or deny the structure, no matter where they are located. This Dungeon is at the center of the southern Local cluster.

Conquer the surrounding Dungeons to create a connection. This Open Dungeon will become the central hub. 

More information will be offered when Owner is in possession of all southern Team Dungeon Crystals. 

Current Crystal count (6/10):

There was no teleportation like he had been expecting. The ground began to shake as the gravestones started to move.

At first, they were just vibrating in place. A few moments later, they ripped themselves from the ground and flew out in all directions.

The giant headstones settled at the far edge of the Formation, soon merging together. They created a ten-foot-high wall around the perimeter.

Some smaller headstones began to attach themselves to the wall, forming stairs and notches on top. Most of the shorter tombstones flew into the air and floated around the Dungeon, taking on a dome-like shape.

The ground began to quake even more as the earth cracked in the center of the Dungeon. A tower slowly began to rise from the foundation.

It took several minutes for the entire structure to be revealed, only stopping when its peak spire touched the centermost floating headstone.

As the two made contact, a small explosion took place. Like landmines going off, all of the tombstones shattered into a fine dust.

Geth was watching all of this take place with Inspection active. As the dust spread in the air, another formation arched out in every direction.

A large dome of Mana covered the entire grounds. It started from the tip of the spire and ended on the outsides of the walls.

Multiple Runes spun in opposite directions around the dome, causing it to constantly move. It reminded Geth of the forcefields seen in sci-fi movies.

The Dungeon was bare. Only the tower, standing more than 120 feet, took up any space on the land.

From the sides of the tower to the wall, there was more than a mile of space in every direction. Hundreds of smaller buildings could fit inside.

\'It seems like it was set up this way to build a small city,\' Geth thought. \'Albus, do you have any insight?\'

\'All I can suggest is that we take the last two Dungeons and see what happens,\' He responded.

\'Last two?\'

\'Yes. Your friends, Blaze and Swole, both currently have a Team Dungeon Crystal and multiple Solo Dungeon Crystals on their person. Take a glance at them using Inspection,\' Albus answered.

He did so and found that he could see a familiar light surrounding their storage items. \'Well, I guess I should have put that together before now.\'

Geth turned to look at the others and saw them spinning in circles to view the wall and tower. He noticed that Blaze was looking directly at the Runes on the dome.

Walking over to him, Geth asked, "What do you think of it?"

"This is very different from the Formations in the cave type Dungeons. Look at the massive Rune directly above the tower," Blaze told him.

Geth did as suggested and noticed a very intricate Rune hovering in the air. Multiple minor Runes were above it and branching out from it.

Blaze continued, "That Rune means Convergence. I don\'t really understand its purpose, however. All of the minor Runes making up the dome are Defense Wards."

Blaze began to draw complex lines in the air, eventually forming a Rune very similar to those floating above.

"Punch it," Blaze told him.

Geth stepped in front of the Rune and threw his fist out at it. A loud ringing could be heard as his fist smashed into the Rune.

A tiny crack formed on its corner. Other than that, Geth couldn\'t push his fist through.

Both of his eyebrows raised a bit. It reminded him of the Barrier Skill that he often used.

He cast Barrier to the side and examined it closely. Upon an up-close inspection, he noticed that the same Rune was etched lightly in multiple places across the spell.

"Ahh, so that\'s how it works," He mumbled. "Blaze, does that mean that you can use any spell as long as you know the Rune?"

"Yes, I can. The only issue I\'ve found is the increased Mana cost, and the time to cast is severely lengthened.

The issues would be resolved if I could find a way to etch Runes inside my mind as the Skill Cards do." He pulled up his sleeve to reveal an ugly scar on his forearm.

"This was something I tested. It is possible to cast spells instantly if the Rune is carved into your skin. The only problems are location and drawing the Rune perfectly."

Geth looked at the scar with great interest.. His friend hadn\'t been idle during this time.
