Unlimited Power - The Arcane Path

As much as everyone wanted to retreat since something very unexpected happened, they couldn't move that much, and they couldn't see the path to the exit of the dungeon. Suzan illuminated the place a little bit, but she quickly ran out of mana. However, at least that let everyone to approach.

"Don't move and don't attack blindly," Tom ordered. "We will just kill ourselves by acting like that."

Leon could illuminate the place using fireballs, but it would be too suspicious if he suddenly learns in such a convenient moment how to create fire. However, he knew he didn't want to die because he held back... again. The best option would be to spam Magma Spears or Ice Pillars, but he would have a hard time explaining those.

Leon created a thin curtain of sand around them in order to find the grim reaper; after that, he also created a massive earth spear. He would end that in a single strike; again, he would have a hard time explaining how Leon could kill a boss in a single strike like that, but it would be better than dying, and he could always fake that he passed out. However, even after several minutes, nothing happened. He was ready to attack at a moment's notice, but the boss didn't do anything.

"What the hell is going on..." Miller muttered.

"Shut... up," Tom said.

Something was off, it was the perfect chance for the grim reaper to wipe them out, but the beast wasn't doing anything, it didn't even summon skeletons. Considering that, it was improbable that the creature was waiting for the help of the next wave of skeletons. Leon only noticed what was going when Suzan collapsed at his knees. He couldn't see her, but she wasn't wounded. So, there was only one reason why that happened.

"The boss is draining our mana..." Leon said.

"I thought I was getting tired due to the tension..." Tom clenched his teeth. "This isn't good."

Although Leon's mana was decreasing, it wasn't by that much. It looked like undead creatures were quite good at absorbing mana, but it couldn't absorb a lot from so many targets. That would explain why the skeleton had to wait for a full day before they could equip their swords, helmets, breastplates, and shields, even though they could create those with only one-tenth of his mana.

"It can't absorb mana fast, and probably it can't attack while it is absorbing mana... this is my chance."

Leon decided to keep that information for himself, for the time being, to recover his energy, he decided to meditate and that made Tom frown, because even without light, he could hear his movements.

"What are you doing, Leonard?" Tom asked.

"Saving my energy while I search for the enemy," Leon answered. "We can't escape since the whole dungeon is covered in darkness, so I will kill the bastard with everything I have."

"Can you do it?" Tom asked.

"I can try," Leon answered.

The monster was troublesome, but it wasn't at the same level as the three-headed earth dragon. So, Leon was sure he could kill it even using only earth magic. However, he was also waiting for Tom and the others to collapse, because he didn't want to show them his hidden cards.

While his teammates fell one by one, Leon used the sand to look for the boss. He found the bastard hiding behind the purple crystal; the bastard was hoping that Leon could hit the crystal and summon a horde of monsters to help the creature. Tom was the last one to fall, and when that happened, Leon created a thirty-meter long earth spear that was sharp as hell. When he finished, he grinned.

"I hope you like this..."

Without a hint of hesitation and not demonstrating any signs of his attacks, Leon fired the spear. Before the beast could understand what just happened, the projectile hit its target, destroying its entire body in an instant. Leon didn't hold back, so several blocks of earth started to fall from the ceiling of the dungeon, luckily when the boss died, the darkness disappeared, and he blocked those stones with his Earth Bullets.

"Phew…"

Leon sighed in relief, even though he could have strengthened the attack by changing the material of the spear, he didn't because even himself couldn't dispose of metal. Anyway, the earth spear became sand and create a pretty big pile of dirt. Leon sat down to rest because someone of his group could have faked their own collapses to see Leon in action. Regardless, he stayed conscious to stop the monsters when they appeared. Surprisingly, Tom got up quite quickly.

"What the…"Tom looked around, confused. "Did you kill it?"

"Yeah, the boss couldn't move and drain our mana at the same time," Leon explained. "So, it received my best attack in full."

"I see… you are unbelievable; you just killed a boss of a difficult dungeon alone." Tom massaged his eyebrows while trying the process of what just happened. "… You fools, for how long do you plan to sleep?"

Tom slapped them on their faces to wake them up, while he was doing that, Leon went to check for his loot. Skeleton's weapons always disappeared when they died since they were made of mana. However, they still could drop items. Unfortunately, Leon didn't get anything in the previous month. So, without any hesitation, he picked the grim reaper scythe that surprisingly didn't disappear.

Grim Reaper's Scythe

It grants the user the skills: Summon Skeleton Knight Lv 20, Summon Skeleton Archer Lv 20, Summon Skeleton Wizard Lv 20.

"I guess this is a jackpot..."

Leon had no use for skeleton knights, but the archers and wizards could perform magic as attacks, and the power of those attacks were defined by Leon's mana and magic power. Although those weren't as impressive as Leon's best spells, thanks to them, Leon didn't have to hold back all that much anymore.
