Conviction - Represented by a purple aura. Conviction (also called Overcome/극복) is fundamentally different from the other four fields. It cannot be obtained through training or physical refinement. Instead, it stems from raw emotional conviction, specifically the overwhelming desire to protect someone or something. It is the only Mastery field that is purely emotion-driven. According to Gapryong Kim, Conviction allows the holder to exercise power beyond their own physical limits, temporarily surpassing what their other Masteries or base stats would normally allow.

However, if this power is pushed too far, it takes a severe toll on the user's body. It has also been implied to carry the ability to block Invisible Attacks, as demonstrated by Jake Kim during the Workers (2nd Affiliate) arc. Because it requires genuine emotional conviction rather than physical training, Conviction is the rarest and most unpredictable form of Mastery. It can't be cultivated deliberately, and fighters who possess it often manifested it during moments of extreme emotional duress rather than calculated preparation.

Durability - Represented by a green aura. Fighters with Durability Mastery have superhuman resilience, able to endure punishment that would incapacitate normal fighters, shrug off powerful blows, and maintain combat effectiveness over extended engagements. During the Incheon arc, it was revealed that Durability Mastery also enhances stamina and recovery speed, which is likely why the color green was chosen (mirroring the common game convention of green representing health).

In combat, Durability Mastery allows a fighter to harden their muscles abnormally, nullifying or dramatically reducing the impact of incoming attacks. This also frees them to commit to heavier offensive output, since they don't need to worry about the toll their own attacks take on their body.

Technique - Represented by a light pink aura. Fighters with Technique Mastery have refined their combat skills to the point where they can think and adapt at extreme speed during a fight, inventing new movements and techniques on the fly, executing complex and dangerous actions with precision, and eliminating all wasted motion from their fighting style.

Technique Mastery is the other prerequisite (alongside Speed) for achieving Invisible Strike. In combat, Technique Mastery fighters can construct tactics in real time, find and exploit openings that others wouldn't notice, and deliver precisely calculated blows that maximize damage while minimizing exposure. The elimination of unnecessary movement also makes them naturally faster and harder to read.

Speed - Represented by a blue aura. Fighters with Speed Mastery are extremely fast, able to cover long distances in moments, dodge attacks that would be unavoidable for normal fighters, and land rapid consecutive blows before opponents can react. Speed Mastery is also one of the prerequisites for achieving Invisible Strike. In combat, Speed Mastery fighters are highly evasive and can overwhelm opponents by attacking from angles they can't track.

The overall speed ceiling rises dramatically, affecting movement, reaction time, and attack delivery simultaneously. A secondary benefit is increased attack power through momentum. Faster strikes naturally carry more force, so Speed Mastery holders hit harder than their raw strength alone would suggest.
