A'Sharad Hett was exceptionally skilled in the Jar'Kai
style of fighting. This talent was evident throughout the Clone Wars,
in which A'Sharad served as a General, often leading his soldiers from
the front through the thickest of the fighting.
A'Sharad often wielded two green lightsabers in battle, his own weapon,
and that of his father. He was able to defeat Aurra Sing in a
lightsaber duel while he was still a Padawan; an impressive feat, considering his own father, a fully trained Jedi Knight, had been unable to defeat Sing. It should be noted, however, that his power was augmented by the hatred he felt towards Sing for murdering his father. This indicates that A'Sharad Hett had discovered a basic understanding of Force Rage, allowing him to boost his ferocity and best Sing.
However, as Darth Krayt, Hett was able to fully master and focus his
usage of Force rage, such as when he dueled Cade Skywalker and Darth
Wyyrlok.
It was his mastery of Jar'Kai that saved Hett from being killed
during Order 66, allowing him to kill the clone troopers who were sent
to execute him. After turning to the dark side, but before becoming a
Sith Lord, Hett engaged the extremely powerful Jedi Master Obi-Wan
Kenobi in a lightsaber duel and proved capable of holding his own
against Kenobi, but was eventually defeated.
