Assassin (Class)

Assassin is one of the standard Servant Classes used in the Holy Grail War. Members of this class are traditionally Servants who employ stealth. Assassins have few notably high stats, but they don’t need them; rather than compete with other Servants directly, the cunning Assassin prefers to cut off their foe’s mana by killing their Master. Assassins do sometimes stand out in Luck, representing their cunning knavery. The class skill most associated with Assassin is Presence Concealment, the ability to pass by other Servants without being detected. Using this skill, Assassins can launch ambushes and catch foes unaware, making them a threat to any team -- and especially to any Master.
