The spear of midnight black was an ancient dark side Force power. It enabled the Force-user to summon the Force and create forge an invisible, deadly spear from dark side energies which could be hurled at opponents, killing or injuring them as if it was a real physical spear.

It is possible that Kyle Katarn used this technique to kill Dark Jedi Boc Aseca in their duel in Valley of the Jedi on Ruusan, forging a spear of midnight black and hurling it at a momentarily distracted Boc's chest, much to the delight of the Sith spirits that were trapped in the valley.

Behind the scenes
While this technique is not available in the computer game Dark Forces II: Jedi Knight, it is described in the novella Dark Forces: Jedi Knight as the method that Katarn uses to kill Boc.
