Form V: Shien / Djem So, The Way of the Krayt Dragon, or The Perseverance Form was the fifth of seven forms recognized as canon by the last Jedi Council for lightsaber combat. It was developed by practitioners of Form III: Soresu, who felt that the defensively-minded form would unnecessarily extend time spent in combat by forcing its users to wait for an opportunity to strike, rather than creating their own openings.

Shien, considered the classical Form V, was more adept at blocking blaster bolts, whereas Djem So, developed later, was designed for lightsaber combat. Both Shien and Djem So were designed to use the opponent's attack against them, as evidenced by Shien's focus on returning blaster bolts to their origin.
