Resonant Spiritual Armament

Resonant Spiritual Armaments (共鳴霊的武装), colloquially known as Devices (デバイス), are an item, usually a weapon, that a Blazer can manifest from their souls.

Summary
Devices are the materialization of a Blazer's soul as a weapon, which can be used in battle. A Device takes on an assortment of different forms and abilities based on the Blazers themselves. The shapes that a Device can take on range from simple weapons like swords or spears to more modern weapons such as firearms or chainsaws. A Device is able to take form as other types of items related to the Blazer's abilities. There are also some Blazers who are able to summon more than one Device or multiple copies of the same Device.

Being the manifestation of a Blazer's soul, Devices are able to withstand a great deal of damage without bending, much less breaking. However, there are cases when a Device does break which results in the Blazer losing consciousness. It is, however, possible to develop resistance against this, however, it needs an extremely strong mental constitution.

A Device can be deployed in «Illusionary Form», as opposed to «Real Form» for practice and/or mock battles, causing damage to a person's stamina instead of actual physical damage. It can also be used if the Blazer doesn't intend to cause real damage to their opponent. Despite a Device not being able to cause damage to an opponent or kill them, attacks that are overwhelming enough can put people in a comatose state.

A Device also serves as a medium for Blazers to utilize their Noble Phantasms, which are their trump cards in battles.

There are rare occurrences where a Device and change or evolve because their Device reflects their inner spirit and everything about them. Therefore, if a Blazer completely "rebuilds" themselves, their Device will change as well. This also includes how many of their Devices they can summon and the size of the device.
