In combat, shinigami utilize a set of combat principles known as Zankensouki. These principles are made in such a way that one may excel in one without suffering for lack of another - or to utilize all four of its categories simultaneously. Divided into four core tenets, they are recognized as Zanjutsu, the art of the sword; Hakuda, the art of hand-to-hand combat; Hohou, the art of fast movement; and Kidou the demon arts.
Advent Humans, relying more on brute force than refined technique, have had their style of fighting dubbed the appropriate Banryoku. Divided into three recognizable areas, a human tends to dabble in at least a measure of all three to ensure the maximum amount of potential.
The three recognizable areas are known as Combat, representing their total capability in close-range combat; Agility, representing their capacity for natural movement and their overall reaction time; and Fortitude, representing a human's ability to withstand and overcome damage. Additionally, an Advent Human utilizes Resonance, which represents an Advent gaining momentum, that rises throughout battle as the human utilizes their other abilities.
Being of shinigami nature in origin, Vizards utilize the majority of their combat skills from Zankensouki, using the same sheet as shinigami. They are separated, however, by the functionality of Rage, representing how much mental influence their Inner Hollow has on their emotional state, and overall control of themselves in a combat situation.
With the cut-throat ideology and nature of their power, Quincies have adopted a code of combat known as Ikorose, focusing on quick elimination of the target while ensuring the survival of the Quincy.
The first tenet, Kyuuzu, determines the Quincy's capability with their Hamayumi - primarily, their accuracy. Namazan, the second tenet, represents the Quincy's ability to evade and maneuver in close-combat situations, and their ability to survive hazards at close-range in general. Finally, Douryuu is the third tenet, determining a Quincy's general movement, natural speed, and ability to react to parse and react to oncoming threats.
What separates Quincy as a whole, however, is their ability to tap into Shuuhaku, a separate pool of energy drawn from the ambient reishi of their surroundings. Shuuhaku is represented as 10% of their base reiatsu while on Earth, and when in reishi-rich environments like Hueco Mundo or Soul Society, that amount is increased by a further 10%.
