Martial Arts

Martial Arts (目の武技, Me no Bugi) are fighting skills used by warriors that hail from the New World. They are considered as one of the powers alongside Talents, Wild Magic, and Runecraft that did not exist in YGGDRASIL.

Background
Martial Arts is made up of techniques that did not exist in YGGDRASIL. Similar powers in YGGDRASIL were called "skills" and they are acquired mainly by players with warrior classes. When using a particular martial art technique, the effects can boost a warrior's physical abilities or sharpening the person's mind and so on. Whereas magic casters are practitioners of Tier Magic, Martial Arts are considered to be the magic of the warrior classes which melee combatants excel at.

One needed sparring partners when practicing the techniques of martial arts. According to Brain, they were the kind of skills mastered during a warrior’s quest for martial perfection. He even contemplates on the idea that martial arts were created to fight beings that were stronger than humans. A warrior needed to anticipate all sorts of circumstances, learn various martial arts, and incorporate them all into one's own strength. This went double for adventurers, who were often plunged into bizarre battle conditions.

On the other hand, Martial Arts consume a user's focus depending on how strong they are. For this reason, there is a limit to how many of its arts can be used at once. Still, a warrior of Gazef Stronoff's caliber can normally use six at a time and, under extreme circumstances, up to seven simultaneously.

While so, Martial Arts is considered a natural-born fighting style developed by the native inhabitants living in the New World. For unknown reasons, players or monsters like the Death Knight from YGGDRASIL are unable to neither demonstrate nor develop any skills close to martial arts' level. There are several warriors like Go Gin in the New World from different races rather than magic casters alone, who are already capable enough of using martial skills with their own physical might without the need for magic.

Furthermore, they can practically utilize martial art techniques in unison, so to enhance their overall power, resistance, and create more devastating combos, using them in succession as one skill altogether. It is possible for other natives such as Hamsuke to be able to learn martial arts over a given period of time while training oneself. There are also methods, like the one used by Climb, who is able to develop and learn a martial skill in deadly battles, from facing blood lust directly against opponents who are stronger than him.

In other instances, Brain could copy and perfect another user's martial skill. Ainz even believes that the concept of martial arts was created as a countermeasure against YGGDRASIL Players. Some warriors, who are considered to be geniuses, can learn Martial Arts themselves when they wouldn't normally be able to learn, during their current level.

Mechanics
Martial Arts are skills that can only be cultivated through intense training. The applications of martial arts are vast, ranging from altering one's physical prowess, magic resistance, strengthening weapons, to even altering the opponent's spatial and temporal awareness.

In terms of acquiring martial skills, it usually takes a novice around a year to achieve. This is through real battle experience, healing when injured, fighting stronger opponents with enhancement magic, etc.

However, Martial Arts are limited through the user's physical and mental stamina. The more powerful a martial art is, the greater mental concentration is needed to fully perform it. Also, this would mean that concentrating too long will fatigue the user's mental and physical stamina over time.

When using it with armor, a miscalculation would result in one being left defenseless before the foes. Therefore, most people would commonly use it with a shield or weapon.

Trivia

 * Since Martial Arts did not exist in YGGDRASIL, Ainz Ooal Gown refers to it as 'the magic of warriors'.
 * Given the overall inspiration of Overlord to D&D, Martial Arts are probably inspired by the "Tome of Battle" Maneuvers.
 * One of Ainz's Death Knights is trained with Hamsuke, to test whether it can learn Martial Arts or not. The result ultimately showed that it was impossible.
 * Ainz uses one of his spells called "Perfect Warrior," enabling him to perform extraordinary feats that make it look like a martial art technique. Even without "Perfect Warrior," Ainz relies on brute strength and his racial abilities to better himself as a warrior and imitating battle stances similar to the experienced warriors like Clementine he fought in the past.
