In the game Spirit Hunter World of Douluo Continent, the Martial Soul system is at the core of the entire combat mechanism. The way Soul Masters fight, their methods of dealing damage, and even support, all revolve around the Martial Souls. Below, we will introduce the Martial Souls in Spirit Hunter World of Douluo Continent. Martial Souls are "carriers of skills" for characters. Players can not only own and freely switch between multiple Martial Souls but also enhance these Martial Souls through Soul Rings, Qualifications, Skills, and Star Upgrades, allowing them to unleash higher combat power.

Martial Soul Positioning
Soul Masters (players) can carry up to four Martial Souls. Different Martial Souls represent different combat styles, such as strong attack, agile attack, defense, control, and support. Each style has its unique skill combinations and combat methods. Martial Souls have five types of skills: basic attacks, initiative skills, soul skills, ultimate skills, and passive skills. Each type of skill has a clear purpose and characteristic. The richness of skill types allows the same Soul Master to present completely different combat modes when switching Martial Souls. For example, strong attack-style Martial Souls often focus on burst damage, while support-style ones excel at enhancing teammates, restoring soul power, and providing shields and team-wide buffs.

Martial Soul Cultivation:
Level
After obtaining a Martial Soul, players can cultivate it in multiple dimensions. First is the Martial Soul level, which is tied to the Soul Master's level and cannot exceed the character's level. Next is the Soul Ring system; each Martial Soul initially can only be equipped with some Soul Rings, but as the Martial Soul level increases, more Soul Ring slots can be unlocked, enabling more complex skill effects. Soul Rings themselves have year differences, and the higher the year, the stronger the bonus, and the more complex the skill effects, such as knockback, stun, pull, burn, silence, and other control and continuous damage abilities, which are all achieved through Soul Rings.

Qualification
The Martial Soul qualification system is an important mechanism that affects attribute growth. Players can manually adjust the base qualifications of each Martial Soul, including preferences for attack, health, spirit, critical hit, and precision, to better fit a certain combat style. The Star Upgrade system requires consuming fragments of the same Martial Soul. After upgrading, it not only significantly increases base attack, health, and defense values but may also activate advanced forms or additional effects of certain skills, forming unique tactical strategies.

Skills
Skills are the core of differentiation for each Martial Soul. Although basic attack skills are the most fundamental form of output, they also have variations, such as some basic attacks that can come with control or damage-increasing states. Initiative skills are like entry skills, triggered immediately when the Soul Master enters the battlefield, used to gain the first move or disrupt the opponent's rhythm. Soul skills, as cooldown skills, are the main force for output or support. Many soul skills can evolve into different forms after unlocking certain year Soul Rings, such as expanding attack range, adding control effects, or causing combo damage. Ultimate skills are the most iconic powerful skills for each Martial Soul, often high-damage output or group control, usually requiring the consumption of soul power to release. Through Soul Ring advancements, the type of ultimate skill can also be replaced, making the combat strategy more varied. Passive skills are always active, some stacking debuffs, others enhancing resistance or skill efficiency, and are an important source for increasing overall strength.

Bonds
Certain specific combinations of Martial Souls, when used together, activate additional attributes, such as increased attack, increased critical hit, and enhanced damage reduction. Therefore, when assembling a Soul Master lineup, players need to consider not only the strength of individual Martial Souls but also the synergy between bonds to maximize combat power output. Additionally, based on the type of Martial Soul, players can flexibly adjust in different battle situations, such as PVP focusing on burst and control, and PVE prioritizing sustainability and support, forming a relatively mature and deep strategic system.

Common Martial Souls:
For example, the "Nine Treasures Pagoda" is a highly representative support-style Martial Soul. It focuses on long-range basic attacks and mark mechanisms. Its initiative skill, while dealing damage, can also grant a Nine Treasures mark. There are six types of marks, including increased attack, defense, soul power recovery, and movement speed. When all six marks are collected, they automatically upgrade to an all-around state, greatly enhancing combat power. In addition to providing increased damage and soul power recovery, the soul skill, after being upgraded, can also provide shields and increase the amount of soul power recovered. Its ultimate skill provides a large shield and a霸体效果,在解锁第四魂环后更是能转化为全队5秒无敌光环,这使得九宝琉璃塔在高强度团队战中有着不可替代的战略地位。
It seems there was an error in the translation. Let me correct and complete the last part:
Its ultimate skill provides a large shield and an invincibility effect. After unlocking the fourth Soul Ring, it can transform into a 5-second invincibility aura for the entire team, making the Nine Treasures Pagoda indispensable in high-intensity team battles.
