Sever Force/Legends

"When you feel the dark side energies turned against you, you must use your Jedi abilities to take power away from an opponent, rather than to inflict harm. This technique blinds your enemy to the Force with a wall of light, a permanent blockage if you so choose, rendering him unable to use Jedi powers. It is difficult. And it is the most devastating attack possible using the powers of the light side. To block a Jedi from the Force&mdash;even a Dark Jedi&mdash;is a terrible thing."

- Odan-Urr, via the Tedryn Holocron

Sever Force was a non-lethal Force power by which a being's connection to the Force was interrupted, or blocked from them with a wall of light-side energy. According to the ancient Jedi scholar Odan-Urr, severing an individual's Force connection was the most powerful attack a Jedi could perform.

While intended to be an attack with usually irreversible consequences, severing an individual's Force connection was not always permanent. When the affected being had the Force restored to them, it returned as a painful and sudden rush of feelings, as the Force immediately allowed the individual to sense everything around them at once. This was the case with Jedi Ben Skywalker, who had his Force connection severed by his cousin and Sith Lord, Darth Caedus. Caedus had blocked his cousin's Force abilities while holding him captive in the Yuuzhan Vong torture device known as the Embrace of Pain.

In times of ancient Jedi, severing Force connections was used as a means of punishment. In 3,951 BBY, Jedi Masters Zez-Kai Ell, Kavar and Vrook Lamar attempted to use this power on the Jedi Exile, but Kreia stopped them not by severing their own Force connections&mdash;rather draining them, and ultimately killing them.

The most extreme case by far was when the Jedi Exile used it unconsciously on herself to shield herself from the devastating effects to those who can sense the Force when the Mass Shadow Generator was activated on the surface of Malachor V, obliterating almost everyone and everything on the planet in the process. The severance was so utter, so complete that the Exile created a wound in the Force in the progress. She did not know this and at first blamed the Jedi Council for severing her connection, believing that they had severed it as a punishment for fighting in the Mandalorian Wars.

During her capture by the Yuuzhan Vong, the Fosh ex-Jedi Vergere used this ability on Jacen Solo.

In a very taxing variation of this technique usable only by those with experience in battle meditation, the Force user could use the Force to sever a target who was heavily tainted or consumed by the dark side. This technique effectively caged the user's power within their own darkness and rendered them blind to the Force, though not dead to it. Nomi Sunrider used this technique on Ulic Qel-Droma after he killed his brother Cay on Ossus.
