I read your post on Jam that mentioned Kliff's Ki and magical abilities being vast. I didn't realize that he was such a genius when it came to Ki and Magic.
Thanks to some recent info I got from @nincopyjasb on the Lightning the Argent novel, we have a broader idea of what happened in Kliff’s fight with the Hydra.
The battleground they fought in was in a region of London, England that was destroyed but over the span of 60 years became known as “Dragged Town” (the story was told from the perspective of events post-2180’s GG1 tournament… which puts the battle itself at or around the year 2120).
So, around 2120 the Sacred Order were struggling against the Hydra and were actually in the process of retreating after trying to fight it for a whole day and night before Kliff finally arrived on the battlefield.
He quickly barks some orders at them to take Military Formation to “win or die trying” and they create a Magic Field to enhance their own strength.
They begin to fire elemental magic projectiles (about the equivalent of explosive shooting stars flying through the sky).
Kliff stands alone in front of the Hydra.
The parasites inside the Hydra’s body spot him and begin to attack, some of the parasites have bodies coated in electric energy and others emitting poison gas from their noses, but none of them can touch him as several dozen of them chase after him all at once.
With a single swing of his Dragonslayer sword he cuts down half the parasites without even touching them directly, knocking aside others simply from the force of his swing.
As Kliff tries to approach the Hydra directly, the beast’s range is too large and manages to attack Kliff’s “7th blind spot” with all its limbs.
He dodges four of the limbs with a sort of “spinning air walk” and jumps again before the remaining three limbs can touch him.
As he dodges the attacks he generates a Ki-barrier around his body and uses something he calls the “stars of plasma” (the elemental spells his men were firing from a distance) as catapults to rebound off of, using his Ki as a repulsion force and “accelerates” the arc of his jumping (basically climbing the spells like platforms on to one of the Hydra’s heads).
The Hydra shakes its body and with two of its snake-like limbs attacks Kliff both from the front and behind, while simultaneously generating a shockwave of roars from its remaining five heads.
Kliff uses his hand and fires a massive Ki blast (Reflex Roar/Bellowing Roar) to repel the shockwave. The explosion from the blast disperses the limbs and Kliff attacks the head, smashing one of the Hydra’s eyes.
His men get excited as the first successful hit lands, but Kliff and the beast know the battle has only just begun…
For 3 days and 3 nights (7 days in total) the battle continues unceasingly…
As Kliff manages to finally cut off 3 of it’s 5 heads and only 4 of it’s sword-like limbs he realizes he can no longer afford to spend time fighting the creature (as he has more important battles to fight) and gives the order for them to begin the sealing process on the Hydra.
They sew its body’s meridians with 13 chain wedges (about the equivalent of a linch pin with chains fixed to it) and place 2 giant boulders on the remaining heads. The purpose of the chains is based on traditional Chinese medicine as a means of blocking the life energy channels (Ki flow) of the beast’s body.
And finally they station a “Watcher” (sentinel) near the sealed Hydra to notify them in case of an emergency or if it breaks free of the seal.
As of October 26th, 2180 the Hydra was still running a diagonostic on the battle it had with Kliff in the form of simulations to the point it could no longer determine which was the original record of the fight and what were merely the results of a projected simulation.
Kliff had fought on the front lines during the Crusades until his 70s before passing his role on to Ky Kiske.
After the original battle, London was left in ruins with only the area where the Hydra was sealed blocked off. Entire nearby buildings were destroyed and miasma emanated from cracks in the ground.
Even in the so-called “safe zones” lava from the ground had boiled out and solidified like waves of hardened volcanic rock, making just traversing the area on foot difficult.
The Sentinel Watcher monitors the Hydra’s vital signs by using “mechanical magic insects” that function as its eyes and relay 600 fps video, audio, IR, and UV frequencies and relays these back to the Sacred Order’s headquarters in Paris as needed.
When the Hydra reacted to Solaria’s “joyful song” the beast only moved its eyes and the earth around it shook, but then briefly thereafter entered it’s diagonostic dreaming state once more (as it could not move from the seal it was under).
