Gu formations (under which Gu Houses are categorized) belong to formation path killer moves and are another typical assembly of many Gu to create a specific effect similar to that of a conventional killer move of other paths.

In contrast to a conventional killer move, a Gu formation needs mental energy, to control the Gu, only in the beginning of the formation being set up and activated. Their specialty is that they persist even longer than a typical Gu House does, and are oftentimes placed in many key locations of large organizations. They have various uses such as teleportation, cloaking their users from investigative methods, raising the efficiency of Gu refinement or wisdom path deduction, as well as defensive formations, to keep intruders away. Immortal Gu formations can be created using immortal materials or even just by setting up a Gu formation with only mortal Gu in an environment with abundant natural dao marks (This, however, requires sufficient attainment in formation path). A formation can also consist of two or more formations, mostly classified into a main-formation and sub-formation.

## Gu Formations VS Battlefield Killer Moves

It is vital not to mistake Gu formations for a type of battlefield killer move. Both can be simply distinguished as Gu formations need to be set up by placing the Gu in a designated area, for example, a Gu formation in the **outside** world needs Gu that are placed in a designated area in the **outside** world. The Gu of battlefield killer moves, on the other hand, can be activated **inside** the immortal aperture and show their effect in the **outside** world.

This makes Gu formations more vulnerable in case of their core Gu being destroyed or otherwise removed.

Gu formations that are destroyed have a *lighter* impact or backlash on the user of the formation compared to when a battlefield killer move is to be destroyed, the user, in this case, can suffer severe injuries or even a life-threatening backlash, making it far safer to use a Gu formation than a battlefield killer move.

## Ancient Formations

Before the usage of Gu Houses became popular, battle formations were widely used. The ancient battle formations had the ability to combine the strength of Gu Masters and allow them to use different Gu and killer moves at the same time (even amplifying their effect), in contrast to a Gu House which only allowed the Gu House's set of abilities to be used. But battle formations are now scarce and a rarity in the current era, the reason for this is their stringent and sometimes even impossibly hard to fulfill requirements to be activated and used. The most basic requirement is that it could only unleash it's full power when only Gu Masters of the same path would use it.

## Trivia

* Before Fang Yuan combined the gu house Myriad Year Flying Warship with Twelve Zodiac battle formation, an ancient battle formation, during the Fate War, no one has ever successfully combined the two in history.
