With every fireball, at least five orcs were blown up into the sky. When they fell down, most of them had already turned into gradually cooling...corpses.
Almost in an instant, the entire orc front was completely plowed by Duke, and at least a thousand people were killed.
But the more serious blow was to morale.
The orcs' momentum of charging forward was like a poor creature being sent to the gallows. Their limbs were still twitching and struggling, but their throats were tightly strangled.
The constant shouting of "Lok-tar ogar!" came to an abrupt end at this moment.
Instead, there were continuous screams.
The third wave is the mysterious Arcane Missiles.
It was completely different from the commonly known arcane missiles. No one had expected that a small arcane missile would cause a terrifying effect like being hit by a human artillery shell. Many orcs screamed, and then their entire bodies turned into a bloody rain, shattered into pieces, and scattered all over the ground.
This scene not only shocked the orcs, but even the Windrunner sisters around Duke, Magni and others were all astonished.
Duke did not answer. He silently looked at the sentence in the system prompt:
"You have activated the top-level metamagic feat Arcane Energy Storm: After activation, your spell damage increases by 100% and mana consumption increases by 50%, lasting for 30 seconds..."
Yes, the power is doubled, but the cost is also halved.
Under such horrific consumption, Duke's master-level magic circuit could not support it at all.
Under the gaze of countless eyes, Duke's hands were filled with mana crystals that kept falling onto the upper armor of the steam tank. These mana crystals, which were invaluable in the eyes of others and filled with mana, were simply poured out of the space bag and passed through Duke's hands, and the mana inside was absorbed.
The crystal block that has lost its magical brilliance is as cheap as the metal shell ejected after a machine gun shot.
The other mage fights with mana, but Duke fights with money!
Moreover, the speed at which money is burned is no different from setting fire to a warehouse full of banknotes.
However, the next second, Duke's magic power suddenly stopped.
"Not good!" More than one Alliance commander screamed on the battlefield.
Mana Burn - this terrifying negative magic that made countless mages shudder, finally came upon Duke.
The purple-blue arcane light that originally lingered on Duke was forcibly driven away, and Duke's hair, fur, and even the wizard robes on his body began to burn. This was not the harmless burning of the fire element, this was a real burning on the body.
"Duke!?" The three Windrunner sisters who had been standing on the top of the tank, guarding Duke, screamed at the same time.
"I'm fine." Without screaming, Duke groaned and decisively activated Ice Barrier!
The surging frost elements in his body quickly drove away the Living Bomb magic from Baron Geddon. A second later, Duke canceled the Ice Barrier and continued to pour magic towards the Horde.
However, just three seconds later, Duke was hit again.
"Ding!" Duke activated Rapid Cooling in one breath, forcibly calming his ice magic circuit, allowing himself to activate Ice Barrier again in a short period of time and destroy the Living Bomb.
The magic attack that had been stagnant for a while was launched again. Duke completely used his own strength to open up a way out of the desperate situation for Uther's charge.
"Duke! That's enough! You've tried your best!" Alleria was not an ignorant woman. Her background as a high elf made her know clearly that even if she mastered Rapid Cooling, the Ice Barrier used by the mage to save his life could only be opened twice in a short period of time.
"Duke——" Vereesa was so anxious that she was about to cry.
Sylvanas looked at Duke with a complicated expression. She wanted to say something, but she remained silent. The longer she spent with Duke, the more she understood why her elder sister and younger sister were so obsessed with this ordinary-looking little human mage...
"No! It's not enough! the Horde's formation has not been opened yet! I have a way that won't cost me my life!"
Soon, everyone knew what Duke's so-called method was.
Duke actually used his magic circuit in turns, not ordinary use, but almost destructive use.
The essence of Mana Burn is to ignite the mana in the magic circuit. The more mana there is, the more damage there is. From another perspective, without mana, there will be no damage.
Duke was risking his life. He concentrated all his mana into a certain magic circuit in a short period of time, and continued to attack with the corresponding magic. When he was hit by the mana burning, he used up all the mana in that magic circuit in the shortest possible time. After the Mana Burning effect was over, even though that magic circuit had been slightly damaged due to the spontaneous combustion, he could immediately use another magic circuit to continue attacking.
If Thunder is broken, use Wind, then Frost, then Fire, and finally Arcane...
In total, Duke was hit by Mana Burn seven times, but he survived them all.
Everyone who witnessed this scene unconsciously shed tears in their eyes.
Being hit by Mana Burn seven times without a high-level priest by his side! Who doesn't know that a mage's mana is much stronger than his life force? This is tantamount to Duke stepping into the gates of hell seven times and then pulling his feet back violently.
Will this be cost-free?
On the contrary, this is an extremely high price that no magician in the world is willing to pay!
For a long time to come, even if Duke used an apprentice-level magic again, it was very likely that the magic power in his body would collapse and he would die on the spot.
"Duke! Enough! That's enough! Leave the rest to us!" With Vereesa on the left and Alleria on the right, the two sisters hugged Duke tightly.
"Okay!" Duke's body was twitching wildly in pain, but a satisfied smile appeared on his face.
The defeat of the Alliance main formation stopped, and the fleeing Alliance soldiers began to shout "Long live the Alliance" and turned around and charged towards the orcs regardless of anything.
A golden blade emitting a sacred aura appeared on the battlefield. It swept across the vast charred land at high speed and cut obliquely into the green ocean.
After Duke's ten rounds of magic finally blasted a bloody path, Uther's twelve paladins perfectly killed in front of the orcs' vanguard and collided with it violently.
Riding a warhorse that was also shining with golden light, Uther rushed into the battlefield, swinging his slender long-handled warhammer like playing polo, drawing a dazzling arc from bottom to top.
"Puff!" With just one hammer, the giant axe blocking in front of him was shattered, as well as the skull of the axe's owner - the orc.
