Marco Barrows. That is the new name he has in this world. It all starts when he decides to fill his free time at work by filling a CYOA after finding it on a forum. He fills the CYOA and creates a building. It is on an Easy Difficulty, but to increase the difficulty and add more points for him to spend, he decides to take drawbacks, and they are horrifying.
The CYOA is called Lt. Ouroumov's Worm CYOA V17, and it is a CYOA set in Worm, a web novel by Wildbow. However, you can change the starting world of your MC, and he picks Harry Potter.
Sadly, because of the Drawbacks he picked, he is an orphan. Lucky for him, the Barrows Family is a wealthy family in the Wizarding World. He is now the only member of a wealthy Pureblood Family, and many people want to marry him for his wealth.
That is also the reason why his parents were killed in the war. According to his new memory, his parents are ambushed while they are about to visit the Ministry and killed. Their main plan is to kill his parents and him in the ambush, but sadly for them, he is sick that day and survives in the mansion.
Lucky for him, the Death Eaters and Voldemort are busy fighting the war as they start an open war with the rest of the British Wizards and Witches. Because of this, he was able to attend Hogwarts and graduate as a proper wizard with 5 O's in NEWT. He has O in DADA, Charm, Transfiguration, Runes, and Enchanting.
He can work as a professor at Hogwarts, but he decides not to do that and instead opens a shop in Diagon Alley. That is the result of his Full-Time Job perk, something that he is grateful for. Whoever sends him here is willing to accept his narrative while making this CYOA build.
Anyway, he also took two drawbacks, as he thought they were free points for him. The first one makes him incapable of revealing the origin of his power and the presence of the Wizarding World. The mundane people can still see them, but he cannot tell anyone about it.
The second one renders him incapable of sharing meta-knowledge with anyone.
Both of them give him points, and he is already planning not to tell anyone. He wants to keep the knowledge to himself. As for his power… He decides to make a theme, and what theme is it? Godslaying.
[Pandora's Child] makes him into a Campione, or Godslayer. He gained a massive boost in his physical strength, and his mana core got bigger, seventy times bigger than what it was. However, what makes him excited is the fact that he has authority. He knows that the CYOA says that he will receive one Authority, but he never thought he would gain it from a well-known Divine Being.
He received authority from Leviathan, Dragon of the Abyss, and Ruler of the Primordial Sea. He receives an authority called {Tyrant of the Deep Sea}, and it is divided into two categories: Active and Passive.
The theme of this authority is the Deep Sea. Let's start with passive abilities. It gives him an Abyssal Sight: Let him see through darkness, illusions, invisibility, and disillusionment spells. It can even let him see someone's emotions, as their emotions appear to be like the movement of water. Chaotic? They might be angry or panicked. Eerily calm? They are holding back something. High and low? They are planning something.
The next one is called Lord of the Ocean. It makes him venerated by all sea-aligned creatures. It also gives him immunity to drowning, chill, aquatic curses, entanglement, and water-based transfiguration.
The last one is the Ruler of the Abyssal Sea. It gives him the ability to control a massive amount of water and even generate some with a thought. Sadly, all the water he generates will always be seawater, and he cannot provide people with drinkable water. Not only that, but this authority also makes him immune to all forms of environmental pressure, including those of the deep sea and the void.
However, when he activates by chanting the incantation, it gets real.
When he activates the authority, he can transform into a sea dragon —a serpent-like dragon with four legs, but without wings —that can cause a massive tsunami and sink an island with ease. Not only that, he can also control the gravity of his water. That means that when his opponents are submerged by water, they will have a hard time leaving. Not only that, the deeper they go, the stronger the gravity becomes to the point that they can get crushed and turned into a ball of meat.
His body becomes even stronger than before, and it takes a considerable amount of damage to hurt him. His control over water also gets stronger. He can now control water a kilometer away from him.
Sadly, there are weaknesses to this authority. When he is turned into a dragon, he is vulnerable to holy-based attacks. Leviathan is a Dragon of the Abyss, and it is weak against holy attacks. It was transferred to him when he turned into a dragon.
Not only that, but because of his nature as Dragon of the Abyss, he cannot last for more than five minutes. It is in the legend that Leviathan cannot go to the surface for long, and it needs to return to the abyss, for it is its home and prison.
The next power is called [Mythender] and is an upgrade of [Pandora's Child].
This upgrade enhances all his abilities and grants him an advantage in battles against supernatural and divine entities. Every strike he unleashes as the Mythender carries an overwhelming essence that pierces through the defenses of gods and mystical entities, inflicting devastating damage upon them, regardless of their divine power.
He possesses an innate talent to comprehend any supernatural being he encounters instantly. This supernatural instinct grants him an intuitive understanding of their strengths and weaknesses, enabling him to exploit them with unparalleled precision, making the most effective use of his abilities.
As the Mythender, he surpasses the strength of a conventional Campione. In battle, he grows stronger while the divine and supernatural beings he faces gradually weaken under the weight of his anti-supernatural essence. Any supernatural effects directed at him are nullified or greatly reduced, as his innate resistance and dominance over the supernatural neutralize their potency.
However, there is one thing that makes this upgrade very powerful.
Unlike Campione, he gains more than one authority when he slays a divine being. He will gain authority from each domain that a God has. Take Thor, for example. He is the God of thunder, storms, strength, protection, fertility, farmers, and free people. He has seven domains, and that means he will get seven authorities from him when he kills Thor.
Not only that, he will also gain their full divinity. That means, it will increase his divinity even more. What does this mean? He doesn't know, but he is excited to find out.
It is a bit different than what is written on the CYOA, but he will not complain about it because that is a major boost.
The last power in the Godslaying theme is [Denial of Heavens] power. It allowed him to defy the gods' authority by nullifying any power derived from a divine source. Moreover, this also weakens any gods, divine beasts, priests, divine champions, and/or prophets fighting against him. The higher the divinity of his opponent, the weaker they would be. However, if the difference in strength between him and his opponent is too large, the debuff will be less.
Sadly, this power has weaknesses. The CYOA does not explicitly state it, but this power has its limits. It can only nullify up to seven authorities for one God. Lucky for him, when God assumes other identities, such as if Zeus changes to Jupiter, this power thinks of that identity as a different God entirely.
This power is weak against God with great authority, but it is powerful against God with many identities.
The [Planeswalker] and [Colored Magic], on the other hand, are powers that choose to let him go around the multiverse to hunt Gods who deserve it.
He is now a Pre-Mending Planeswalker, someone who can destroy a world if given enough time and travel the Blind Eternities unhindered. What makes a pre-mending planeswalker so powerful? Well, all the cards in m:tg are spells and things pre-mending planeswalker can summon.
As long as he has enough mana, he can get by tapping into the land; he can do basically anything.
And [Colored Magic] is the power that lets him do anything with the five colored mana: Red, Green, Blue, Black, and White. Planeswalker can do anything with the mana as long as he has enough, and Colored Magic lets him refine the mana to do things using less mana.
Not only that, it also opens him to Artifice speciality, where he can create magical artifacts. What? ROB (Random Omnipotent Being) gives him knowledge in enchanting and a Magical Trunk Shop. There is no way he will waste an opportunity to use his new power to expand his business.
He doesn't have any big goals or something he wants in this second life. He wants to enjoy his second life and test his powers. Maybe save a world or two, but overall, he will enjoy his second life.
