Might need some editing, but here's the initial Berserker.

[center][img]https://i.imgur.com/t3UevWz.png[/img]

[b]True Name[/b]: Rostam (White)

[b]Gender[/b]: Male

[b]Attribute[/b]: 

[b]Era[/b]: Age of the Gods

[b]Area[/b]: Persia

[b]Alignment[/b]: Lawful Mad

[b]Weapon[/b]: Sword and Mace[/center]

[b]Background[/b]:

One of the greatest heroes of Persia, born to a heroic legacy going back generations. Famous for various episodes, including killing a mad elephant single-handedly at a young age, going through seven labours to rescue his king from a demon, unknowingly killing his own son, and his legendary fight with the hero Esfandyar. 

This, however, is not that Rostam. After defeating the White Demon, Rostam took its skull as a helmet. Naturally, the demon would extend its influence into corrupting the hero - but Rostam’s bravery and devotion to Ahura Mazda were enough to hold this off with little difficulty. 

Within the Berserker class container, however, this corruption was able to take hold. Various anecdotes exist of Rostam acting in anger, both towards his own horse and his enemies, but this incarnation of Rostam is more than simply a berserk Rostam. Rather, this is an ‘inhuman’, fallen version of the hero.

[b]Parameters[/b]:

STR: A+ ||| END: B+ ||| AGI: A ||| MAN: C ||| LCK: C

[b]Class Skills[/b]

Demon Enhancement: A

A mutation of Mad Enhancement based on the influence of the White Demon, whose skull Rostam took as a helmet. 

Rather than boosting Parameters, the very nature of one’s existence is changed, becoming a Monstrous Human. Physical capabilities and senses are increased beyond the abilities of humans, though they still cannot compare to that of a naturally born monster. As with Mad Enhancement, reasoning capabilities are lost almost completely. 

Though the White Demon and Rostam were both intelligent beings, the dissonance between them has resulted in a complete suppression of personality, leaving a raging monstrosity that simply obeys the commands of its Master. 

[b]Personal Skills[/b]

Mana Burst (Storm): A

The storm magic of the White Demon, integrated into Rostam’s being. The ability to infuse mana into one’s body and weapons and expel it, creating an effect similar to a jet burst by using large amounts of Magical Energy.

In this case, winds are also created by the effect, and can be used as a ranged attack. 

Eye of the Mind (False): B

A danger-avoidance ability based on intuition, gained through various struggles and journeys. Remains effective despite Rostam’s madness as it is honed to an instinct. 

The skill of a hero able to intuit his way through various trials and fights with beasts and heroes alike. 

Bravery: B+ 

An ability to avoid mental influences of various kinds that also increases the damage dealt to opponents. A skill allowing one to combat various raging beasts, even as a young child. 

Fundamentally sealed by Demon Enhancement. 

[b]Noble Phantasms[/b]

[b]Div-E Sepid
White (Black)
[/b]

D Rank Anti-Unit
Range: 0-5
Maximum Targets: 

The absolute darkness of Div-E Sepid’s cave, and the blindness it inflicted on others, though weakened considerably from its true use by the demon. 

A darkness that spills endlessly from Rostam’s heart in increasing amounts; a method of inflicting blindness on one’s foes. It has no physical presence, but offers resistance when moved through. It obscures sight completely, but also somewhat reduces various other senses of those within it. 

By stopping in one area for long enough, the darkness pools and creates a lair of shadows. Naturally, Rostam’s own senses are largely unhindered by it, so this area forms a perfect hunting ground for the Berserker. 

It cannot be dissipated by wind or force, but light causes it to decay, and holy rites can nullify it entirely. 

[b]Babr-E Bayan 
Seven Labours[/b]

B Rank Anti-Unit (Self)
Range: 0
Maximum Targets: 7

The Multiple-layered defensive coat of Rostam. A powerful defense that includes the skin of a dragon. In its initial form, its defensive abilities simply reduce all incoming damage, even from Noble Phantasms, by 30%. 

Its true ability, however, is the capacity to grow with each victory Rostam claims. To a maximum of seven victories, equal to the number of trials he overcame while hunting the White Demon, Rostam can conceptually integrate the defensive capabilities of each foe he defeats. 

As a Berserker, this ability takes the form of an automatic defensive ability with no invocation necessary. In addition, the integration of a defeated opponent’s defenses is automatic, though the case may be different for a sane Rostam.[/hider]
