Notable Attacks/Techniques:

Tsubame Gaeshi: The fabled technique of the legendary Sasaki Kojirou, who was said to be able to cut down a swallow in mid-flight. This sword technique is used by Servant Assassin during the Fifth Holy Grail War. Although Assassin does not possess a Noble Phantasm, Tsubame Gaeshi allows Assassin to match Saber' in combat. It is the utmost and sole technique achieved by the man who took on the name of "Sasaki Kojirou" as Assassin; a sword attack that consists of three literally concurrent slashes. Like Gae Bolg, it is impossible to avoid, albeit through different mechanics. Tsubame Gaeshi causes what is known as the Dimensional Refraction Phenomenon (the same property possessed by the Jewel Sword). As this technique is born of prodigious skill instead of a magical ability, it requires no additional prana beyond what Assassin needs to move, although a level foundation is necessary to ensure perfect execution. Otherwise he can only send the initial two slashes thus it can be still dodged somehow.
