Clarent Proto: Demonic Sword of Shining Brilliant Royalty

An unrevealed D++-A++ Noble Phantasm, belonging to the Mordred of Proto Arthur.

If Excalibur Proto was ornate and emanated holiness, golden and the word beauty would only desecrate its splendor, shining and glowing with golden luster, a blade that promises victory.

Then Clarent Proto was a practical sword, it's overall design was similar, a slightly wider guard and a large dual edged blade. Its blades were red as blood and the grip was black as the night, the guard shone with silver, silver more beautiful than anything. A dark malevolent aura surrounds it and whoever takes hold of it would feel their energy be sapped if they were unworthy.

Just like Excalibur Proto, Clarent Proto was sealed but unlike the knights that execute seal 13, this sword was sealed by Mordred himself with the help of his mother. Not because it needed to, but simply because he wanted to mimic Arthur's own sword.

"Rule 13, Rebellion Start"

The rules to unseal the 13 are specific rules that was specifically made to fit the situation he found himself heading to.

13 Different Mordreds will appear in a ghostly state.

"Rule 1 - You must hate the enemy"

"Rule 2 - You must not harbor thoughts of mercy"

"Rule 3 - The battle must be one against someone of worth"

"Rule 4 - There must be something to gain in killing the enemy"

"Rule 5 - You must cause destruction"

"Rule 6 - The battle must be 1 against 1"

"Rule 7 - The enemy must be aware of your identity"

"Rule 8 - You must not back down whatsoever"

"Rule 9 - Your life must be in danger"

"Rule 10 - Casualties must be ignored"

"Rule 11 - Your pride must be at stake"

"Rule 12 - The sword must not acknowledge you"

"Rule 13 - The enemy is Arthur Pendragon"

"Camelot must fall, Arthur must die, this sword utters the core of treachery, give it blood and rebel against my beautiful father!"

"CLA–RENT!"

"BLOOD ARTHUR!"

Each seal increases the power and size of the black red lightning beam, at the complete unleashing, Clarent can successfully destroy and wipe out and entire country.

The minimum to unleash the attack is 8 seals, anything lower would only clad Clarent is red lightning that saps mana to continuously fuel it, the sword at that state would increase the speed, power, durability of the user corresponding to it's rank.

1 seal = 6x increase

2 seal = 8x increase

3 seal = 13x increase

4 seal = 16x increase

5 seal = 19x increase

6 seal = 20x increase

7 seal = 400x increase (note: this number of seals specifically unleashed is very, very rare because it's not only 1 step away from 8 seals but also a hard number to come across when fighting enemies, especially the way the rules are)

Clarent Proto is a sword the eats mana, mainly because the wielder is usually unworthy and it needs another source of power if it's main battery– the faerie magic– isn't available.

The sword is 1 meter and a half long, and 5 inches wide, a quasi buster sword that grows lighter as you unlock seals.

Minimum amount of Mana required to activate the sword

Intelligence: 50

When using the minimum power beam attack

Intelligence: 100

When the sword is completely unsealed

Intelligence: 150

The sword can be activated even if you lack the mana.

Just don't expect to live if you do, because Clarent will use even life force if the choice was given.
