Incarnation

is the process of a spiritual body gaining a physical body through some magical process.
==Characteristics==
The Fuyuki Greater Grail is capable of incarnating Servants, Heroic Spirits summoned from the Throne of Heroes. Direct contact with it grants them a body that no longer requires the upkeep of a Master to exist, allowing them to become a firm existence that can remain in the world indefinitely.Fate/Apocrypha Volume 3: Triumphal Return of the Saint - Prologue They still need a connection to the Master or another source of magical energy to retain the ability to use their power as a Servant, else they'll have a constitution similar to that of a human. While able to utilize their power as a Servant and Noble Phantasms with a magical energy source, they lose the ability to return to spiritual form. The body of flesh possesses the capacity to age, but abilities like Amakusa Shirou Tokisada's Left Hand - Xanadu Matrix and Right Hand - Evil Eater can work to passively confer agelessness even without magical energy upkeep.
In the case of the Fuyuki Greater Grail corrupted by Angra Mainyu, the Holy Grail Mud also has the effect of blackening the affected Servants. Only those with powerful egos capable of rejecting the influence like Gilgamesh are able to receive incarnation from the corrupted Greater Grail without being blackened as well.Fate/stay night - Fate route - Day 15: Utopia - stay Night (II)Fate/Zero Volume 4: Flames of Purgatory - Act 16 Part 10 -03:11:56 Servants can't normally have children because they are spiritual existences, but for a Servant who has been incarnated it might be possible.Fate/Apocrypha Volume 3: Triumphal Return of the Saint - Chapter 4
