Spiritual Body and Material Body

Spiritual Body and Material Body

“Spiritual Body” is a word that describes an existence with spiritual properties. In other words, a shape is constructed without relying on components with physical properties. On the other hand, “Material Body” means something that is identical in structure as our flesh bodies. A Material Body, just like us, cannot walk through walls, and will hurt and become wounded when beaten with an iron baton. However, a Spirit Body is capable of completely disregarding such physical interference. Attacking a Spiritual Body with a baton or sword (unless they are magical items) will only hit empty space.

When Servants materialise, they acquire Material Bodies in this world. They can also switch to Spiritual Bodies through their will. Spiritual Bodies have the advantages such as low mana consumption, and difficult to be detected by enemies. One of the properties of a Spiritual Body is that it is unaffected by physical interference, but conversely it is difficult for a Spiritual Body to affect a Material Body. As a result, Servants Materialise when engaging in combat.
