Assassin

, Silent Killer and , is one of the Four Cavalry Classes among the seven standard Servant classes summoned for the Holy Grail War. 
==Qualifications==
Within certain Holy Grail War structures, the only qualifying Heroic Spirits are the nineteen Hassan-i-Sabbah due to the etymology of the very word Assassin being tied to them.
 Within the Fuyuki Holy Grail War, it is said to be fixed in the system itself that Hassan will always be summoned,Fate/Apocrypha Volume 1: Apocrypha: Great Holy Grail War - Chapter 2 Part 1 but there is a small chance, so low as to be considered nonexistent, that another will answer the summons.Fate/Apocrypha Volume 3: Triumphal Return of the Saint - Chapter 3 Part 7 The existence of Sasaki Kojiro is an abberation within that system due to his unique circumstances.
Within the world of Fate/Apocrypha, the Subcategory Holy Grail War led to a proliferation in the number of Hassans summoned, a "golden era" where Assassins were a great menace because, on top of their mana consumption being low, killing Masters was far easier than battles between Servants. However, this resulted in all of their True Names and Noble Phantasms being documented, and countermeasures against them were taken, causing the Hassan boom to fall into decline. Masters eventually began adding additional lines to the summoning incantations and bringing catalysts not associated with Hassan to call upon different Heroic Spirits.
Within other systems, there is no limit on the summoning of other Heroic Spirits.
==Skills and characteristics==
For the Hassan-i-Sabbah, they lack glamorous legends, so they are known to possess low attributes. Their very lifeline in battle is reliance on Presence Concealment.
