Physics The Greatest Magic

The death knight was preparing another orb to fire at any second, so I had to think of something quick.

"Honestly, we're already at a huge disadvantage by not having a priest, The only thing we can do now, is weaken it," I replied

The two girls nodded at my reply

"I'll go fight in close and fight it, you two prepare strong range attacks to hit it. Weak ones won't have any effect." I said

"Huh?! Are you crazy? That thing's strength is on par with Rank monsters! I'm sure even rose had difficulties fighting it!" Serena said

"I agree with Serena, I don't think you should enter his range. I can feel it from here, he's a lot stronger than the spider..."

"It's fine, I may not be stronger than Rose but I can use magic at close range, now the problem is his armou-"

I was interrupted by a bigger version of the previous fire Orb heading my way, it was twice the size of the previous one.

"Furtim, Velox!"

With Velox, I managed to propel the three of us to the other side of the room so that the blast wouldn't reach us. I also cast Furtim in hopes that he wouldn't notice.

"Anyways, That's the plan," I said

I could tell that despite being invisible, the death knight could see or sense us. It didn't charge another orb instead it faced our direction as if it was waiting.

I deactivated furtim and descended to the ground along with Serena and Ariel

"If it gets too dangerous, We'll retreat. Velox!"

I put a lot more power on Velox and increased the wind pressure to increase the speed and distance of when it would propel me. After it was ready, I propelled myself straight at the death knight with my daggers at hand.

The Death knight who saw me coming pulled out his longsword from the scabbard on his back. The sword was shrouded in black flames.

While midair, once I was finally 3 meters away from it, I simultaneously swung both of my daggers diagonally at the death knight. He easily blocked both swings with his sword and with a single push, he sent me back 2 meters.

Despite being pushed back, I remained balanced, but I had lost all my momentum. Seeing it as an opening, the Death knight swung at me diagonally but I dodged it by taking a jumping back.

I was sweating heavily due to the pressure and with my gloves, wiped a bit of it off my face, In the corner of my eyes I noticed a bit of red on my gloves.

"Blood?" I muttered

I hadn't been able to completely dodge his swing. If I was a second slower I could have died.

"If I keep holding back, I might die. I'm not sure I wanna kick the bucket yet so..."

I looked over at the death knight and he stood there as if he were waiting for my next attack.

"Triple Cast: Ignis, Glacies, Ventus."

The instant I cast that the magic stones on my glove began to glow and, 2 ice spikes, flames and wind blades were formed around me.

"How about we start round 2?" I asked as I lept at him.

I swung my right dagger vertically and he parried it by swinging his sword. The parry made me lose balance and sent me back. Faster than before, he took the opportunity I had lost balance to slash me in the air.

The moment he was about to swing his blade, I propelled one of my ice spikes at his shoulder. He easily broke the spike by swinging his fire sword, the swing was heading straight at my head. Before it reached it, I Propelled myself straight to the ground and aimed at its open torso

I propelled all the of the Spikes, blades and flames I had remaining at his torso in an attempt to blow him off, but because of that, I was open. Before my attacks reached him, he had already swung his sword vertically at me.

Death, that was the only word that could come to my mind. I was

Even if time had slowed down, there was nothing I could do. I was going to die.

As I saw his sword, slowly get inches closer to my head, I noticed him slow down after getting hit by my magic barrage. A small frozen hole was formed on his chest-plate and I could see his magic core inside of his skeletons rib cage.

The second he slowed down, A thought went past my head. 'Not yet', and at that moment nearly all my magic power subconsciously burst out as if it were trying to protect me. Everything within my radius was frozen.

The death knight and his sword were completely frozen. A split second later, A Flaming Wind Spear came flying out of Ariel and Serena direction and pierced the Death right in its core.

The core's colour changed from red to purple and the glow in its eyes died out.

Seeing this, I let out a relieved sigh and walked up to Ariel and Serena.

As I got closer I noticed that both Ariel and Serena had tears flowing down their faces

"Idiot! I thought that you were going to die! I told you that it was a bad idea!" Shouted Serena with puffy eyes as she lightly punched me

"I thought we weren't going to make it..." Said Ariel as tears continued to flow down her face

"Hey, It's fine, you were able to make it and that's all that matters," I said

"Only because you managed to freeze it. Since when did you have a spell that strong?" Serena as she wiped her eyes

"I don't know. my magic subconsciously burst out" I replied

"What? How do you-"

"More importantly, I was able to save up a fair amount of magic thanks to the magic stones, but they completely ran out of juice. How long until it resurrects?" I asked

"According to what I've heard it's 5-10 minutes it gets longer the more you kill it. However, it'll be significantly weaker after it resurrects itself." Serena Said

"Weaker... When we were fighting, I wasn't even able to enter a proper clash with it. It blocks every Swing I threw and whenever it parried I would either get flung back or lose my balance." I said

His strength is definitely higher than The B-Rank adventurer I fought. If I want to be him, I'll have to transfer even more magic to my body.

"It's strong, It's a bad idea to try to take him on without a priest, I believe we should retreat."

"20 minutes is enough time... We're retreating."

"Okay, but before that, I wasn't sure how to bring this up but..." Serena said

"Your hair, Look at your reflection," Ariel said

"O-Okay..? Aqua."

A ball of water was formed in front of me and I used it to stare at my reflection.

"What!?" I shouted

My recently short spikey blonde hair had turned a Mixture of Black and white.

"When? How?" I asked

"It happened right before you froze The death knight, I've heard side effects when something happens to your mana pool, or when a sudden event occurs. This might be one of the effects of your magic bursting out at once..." Serena said

"So I'm guessing the reason why it's colour is partly white because the element I used was ice?"

"Probably..." Serena said

"Nevermind, Let's just get out of here," I said as we walked to the entrance

The giant door which led to the boss room had closed itself after we were all inside. I pulled at the door with magic strengthening and it wouldn't budge. I tried cutting it open with my blades but there was barely a scratch.

"Yep, We're stuck inside," I said

"I thought as much... I'm guessing the only way to open the door is by beating the boss or if someone opens it from the other side." Said Serena as she let out a sigh

"Serena, what sort of holy spell do you need to truly beat it?" Ariel asked

"As long as it's weakened or in the death state, any holy spell will do, even healing as it has an opposite effect on the undead." Said, Serena

"Eh? Healing works?" I asked

"Yeah, but if you have a high level one, you won't even need to fight it." Said, Serena

"So healing works... Alright, I don't have any time to waste." I said

I lept towards the frozen site where both the ground and the Death Knight had been frozen and in a rush, placed my arms in the direction of its core as I stood in front of the frozen knight.

The core's colour was hastily returning to it's original red and fire was starting to come out of the sword. The ice around it began to melt.

"Percuro," I muttered

My hand began to glow in a golden light. The Death Knight had now fully awoken and began to struggle in the ice. The light was working.

"That light... When did he..?" Asked Serena

The ice around the sword had completely evaporated and with his unfrozen arm, he tried to interrupt my spell.

His movements were slower so I was able to dodge his swings without interrupting the spell, however, with each swing he would end up hitting the ice which covered his body and eventually he managed to get out.

However, by the time he got out, he was near the point of death, I was also running out of magic myself. Percuro is a heavy spell... I created it in case of emergencies. Back when I wasn't able to heal Ariel I realised that without a priest, the least I could do was learn a healing spell.

Its movements were much slower than before, The fire on the sword was dim, and whenever it would swing, it looked as if it was standing still. I was also getting slower and weaker, but I had more energy than it, so I didn't deactivate the spell not once.

As it tried to lift its sword it noticed that it couldn't and it that moment, I increased the amount of power being poured into my healing spell and let it all out at once.

The dim purple light in its core changed to black and the stone broke, releasing a black miasma which disappeared into the air. The Death knight's skeleton turned to ash and all that remained was its armour.

"W-We did it..." I muttered and gave a thumbs up to Ariel and Serena before collapsing to the ground

The Adrenaline had finally caught up. I was completely out of fuel. My magic capacity has definitely been getting bigger. And for the first time, I didn't faint after using it all up...
