A complete guide to all features of the Sung Jinwoo System

The following article contains spoilers for solo leveling.

solo leveling It can already be said to be one of the best animes of this decade, as it was able to captivate traditional shonen fans with its isekai-style story featuring an overpowering protagonist. Seong Jin-woo is not simply overwhelmed. The concept of him as a Player of the System is supposed to make him secretly undefeated. Like many recent anime series solo leveling It relies on a video game-like model of leveling up your character. In this case, only he can level up, and that's the fun of it.

As a result, Jinwoo has a variety of abilities and skills that can be used both in battle and outside of battle. With his powerful actions as the Shadow Lord, he is establishing himself as the best while never forgetting the reason he became a Hunter in the first place: to help his family. The system isn't overly complicated, but let's take a quick look at how strong he can become by analyzing Jinwoo's abilities in the story.

Solo leveling meets expectations so far Jinwoo Seong - Special

Solo Leveling: Seong Jin-woo’s biggest weakness in animation

Even though Seong Jin-woo is the world's strongest S-class hunter, he still has a notable weakness.

Seong Jin-Woo’s solo leveling ability

Seong Jin-Woo, who was named Player of the System, gained his first unique ability: Level Up. As a result, he was eventually able to rise from E rank to S rank and become the best hunter of all time. When Ashborne chose him as his successor, Jinwoo became the Shadow Lord and slowly began to inherit Ashborne's skills and abilities.

As a Shadow Lord, Jin-Woo has acquired many abilities more related to his status (to put it in a more “game” way). For example, he is incredibly strong (physically), fast, and resilient to damage (this would be his endurance ability). Additionally, the learning rate, including combat skills, has become incredibly fast, and for some reason, the aging process has also slowed down.

His abilities also include memory manipulation and control over shadows and darkness. He can also create and open gates, talk to monsters in their native language, and store an unlimited number of items. Jinwoo also has a strong will, which may seem unrelated to his status as Player of the System, but may be the reason why he was chosen.

Store items and gain stat points

  • Jinwoo can choose how to allocate stat points.

  • He can store an unlimited number of items.

Jinwoo levels up like a video game character by earning status points that he can allocate as he pleases. He can therefore focus on some attributes if he needs specific abilities or skills, and like most RPG players, he can customize his build and tailor his growth to the upcoming challenges.

There's no need to get angry to kill dirty bastards like you.

Coupled with the fact that he can store an unlimited amount of all kinds of items, Jinwoo can come up with any strategy without relying solely on his own abilities. Because you can summon any gear at a moment's notice without the constraints of carrying capacity or the hassle of lugging around a huge hiking bag.

Jinwoo has many active and passive skills in addition to abilities more related to his stats. In other words, it is an ability that can be used in battle. Active skills, as the name suggests, require activation and often consume mana, while passive skills are continuously activated regardless of the user's will.

Now, let’s take a look at each skill included in Jinwoo’s set. First, let's look at his passive skills. Healing Will allows you to regenerate from non-lethal damage. If you live long, you become immune to all status ailments. Detoxification cleanses the body from toxins and poisons, including alcohol. Tenacity reduces damage taken when health is below 30%. Lastly, Advanced Dagger Techniques increases dagger damage by 33%.

His active skills include stealth, which allows for camouflage. Bloodlust allows you to threaten your target into submission and even reduce their stats by up to 50%. Jinwoo can increase his speed using Quicksilver. Cleave allows you to aim better and deal lethal damage. Dagger Rush creates a 'dagger barrier' around the target and attacks from all directions. The authority of a ruler allows him to control things with his mind. Last on the list is Dragon's Fear, which can cause your target to panic and lower their health.

The core of Seong Jin-woo’s power is his job ability.

In addition to active and passive skills, Jinwoo also has unique skills as his job class, Shadow Lord, in an RPG-like system. Perhaps the most important of these is Shadow Extraction, which allows you to create an army of shadows by extracting the souls of defeated enemies. Associated with this skill is also Shadow Preservation (also known as Shadow Save). Jinwoo can monitor his statistics by ‘sensing’ whether his shadow is okay.

He can also use Shadow Exchange to exchange places with his Shadows and instantly travel anywhere. Lastly, thanks to the Sovereign's Realm, Jinwoo can also increase the power of all activated shadows. Being a Shadow Lord is not only convenient, it takes Jinwoo to a whole new level compared to S-class hunters and monsters.
