Core Techniques

Nen Categories

Nen Beasts and Constructs

• Animal-type Nen Beasts — Commonly assist in combat, reconnaissance, or coordinated attacks; their form often reflects an animal's traits. 13
• Phoenix — Lu Qi's innate bird-type Nen Beast, originally acquired through Sign-in. It can heal severe injuries, merge with Lu Qi, grant fire immunity, and manifest flame wings for flight. 1 13 14 59
• Elemental creation Nen Beasts — Basen Challenge victors can gain summonable elemental Nen Beasts. They can be repeatedly called by spending Nen unless their cores are destroyed, and may grow stronger through training. 134
• Rule-based Nen Beasts — The Seven Deadly Sins Nen Beasts are intangible, cannot be seen even with Gyo, and influence targets through rule-like effects rather than direct combat. 166
• Nen Beast abilities — The revised Holy Grail War can safely awaken Nen in non-users and grant a Nen Beast ability without conventional ability training. 434

Ability Development and Limitations

• A well-rounded “mountain-shaped” Nen user is highly skilled in their main category while remaining competent in others, allowing them to answer more situations in battle. 6 94
• Developing many techniques improves adaptability, but maintaining several abilities at once demands substantial Nen reserves. 59 282
• Even a user outside a category can achieve powerful results through training; percentage affinity does not alone determine practical strength. 282
• Rule-based abilities are particularly dangerous because they can impose effects such as Forced Zetsu once their conditions are met. 248
• External Nen can bypass some Forced Zetsu effects. Users under Lu Qi's Divine Tree Contract may still fight with contracted Nen, though they cannot use their personal abilities. 248
• Exorcism removes or counters Nen effects, but the Exorcist must bear a corresponding burden; severe Nen may demand an extreme cost to remove. 459
• Nen capacity generally peaks during a user's physical prime before declining with age, affecting the scale of techniques such as Ken and Ko. 261

Divine Script and Nen Tools

• Divine Script is a Nen-related written system with inherent special power. It is used to reinforce Fighting Tournament arenas against damage from Nen users. 21
• Divine Script can be incorporated into weapons and equipment to amplify their effects. A short sword engraved with it gains enhanced sharpness when infused with Nen. 261
• Divine Script Creations can provide defenses against external Nen abilities, such as preventing Hisoka's Bungee Gum from attaching to its wearer. 259
• Nen Tools may persist after a user's death through Post-Mortem Nen, becoming stronger but cursed and imposing costs on later users. 163

Nen Awakening Methods

Role in the Novel

• Lu Qi begins the story as a natural Nen user whose transformed Sharingan and Phoenix are both Nen-based abilities. 1
• Nen becomes central to Heavenly Arena combat, where fighters increasingly use ranged Emission attacks, rule-based abilities, Divine Script, and multi-category techniques to probe opponents. 59 135
• Lu Qi's reforms make formal Nen education more accessible through martial arts halls, awakening technology, Nen Cooking, and public combat systems. 194 197 250
• The spread of Nen changes Keli City and the Heavenly Arena: combatants encounter Nen users even from the first floor, while the fighter profession becomes increasingly competitive. 370
• Nen's wider availability also creates new dangers, including crimes involving difficult-to-detect abilities and the possibility of mass-producing Nen-capable soldiers. 427 434
• Parallel-world travel and Secret Realm Dungeons demonstrate Nen's potential to affect space, worlds, artificial environments, and large-scale social systems. 262 263 428
