What You Need to Know About The Acolyte’s Lightsaber-Shorting Metal

With a swing of a wrist gauntlet, and the head-butt of a sinister helmet, The Acolyte’s mysterious dim Stranger carved a route into Star Wars heritage this week with a single, shocking transfer: strikes that despatched the laser blades of his Jedi foes sputtering out of existence. But while we have located lightsaber-resistant solution in Star Wars lots currently, what could bring about this bizarre impact? An notorious material from the Expanded Universe.

What Is Cortosis?

A extremely uncommon and definitely brittle supplies, cortosis was incredibly initial introduced in 1998 novel I, Jedi by Michael Stackpole. On significant of its rarity, cortosis was exceptionally difficult to mine thanks to its conductive qualities. Like several other sources in the galaxy substantially, far away, it was in a position of resistance to traditional power weapons like blasters—but in contrast to other men and women, cortosis found a location of interest with the discovery that it could also execute the electrical energy of a lightsaber blade, shorting out the weapon for a period of time of up to many minutes.

Even though cortosis featured closely in the Expanded Universe as a premiere anti-Jedi material—although some interpretations of it handled it like any other electrical energy-resistant metals—it did also make its way back once again into present continuity rather early on. Just right after initial becoming canonized in the 2015 Rebels prequel novel A New Dawn, by John Jackson Miller, cortosis has created appearances in numerous comics, mainly Darth Vader and Aphra, but its most distinguished general appear prior to its use in The Acolyte as the supplies the Stranger’s helmet is created out of was in Timothy Zahn’s Thrawn: Alliances in 2018.

There, Anakin Skywalker, Padmé Amidala, and the Chiss Expansionary Defense Energy officer identified as Mitth’raw’nuruodo—the foreseeable future Grand Admiral Thrawn—discovered a cortosis mine on the earth Mokivj, which was remaining employed to establish a differ of cortosis-improved Tremendous Fight Droids (as successfully as, at the behest of Darth Sidious, cortosis-improved Clone Trooper armor to be created use of by means of Acquire 66). The trio destroyed the mine, but at excellent charge to Mokivj itself, when Anakin failed to account for cortosis’ specific strength-redirection properties, sparking volcanic workout that at some point radically transformed a lot of the world’s ecosystem.

How Does Cortosis Do the job?

In every single the old Expanded Universe and most up-to-date continuity, cortosis fibers knowledgeable higher strength absorption and conduction properties, developing the directed power of a blaster bolt that struck the solution dissipate across the fibers with negligible troubles. Even though this trait is widespread in other components in the galaxy a lot, substantially absent, cortosis’ critical absorption and conduction is specific, to the position that striking it with an energy blade like a lightsaber’s would trigger the energy location defending the blade to dissipate, causing a responses loop that would briefly shut down the lightsaber itself. Former Star Wars solution has been inconsistent in just how in depth a lightsaber is disabled by cortosis—in some situations, it is only a avoid-hole, and a de-activated lightsaber can be quickly re-activated in other folks, the weapon is rendered inoperative for many minutes.

Despite the fact that The Acolyte supplied our initially on-show glimpse at cortosis in action, it also seemingly released a property it is under no circumstances knowledgeable correct prior to. Despite the fact that dueling Jedi Grasp Sol, the Stranger implies that his cortosis mask also inhibits telepathy in some way, telling the Jedi that he refuses to get his mask off so Sol just can not study his views. Irrespective of no matter if that is grandstanding on the Stranger’s element or an actual new property of cortosis by itself, obtaining mentioned that, continues to be to be viewed.

What Other Sources Resist Lightsabers?

Like we stated, cortosis is far from the only supplies in Star Wars capable of blocking a lightsaber blade in either the Expanded Universe or present-day continuity. Of study course, we have the Mandalorian iron, beskar, but there is also phrik—the steel alloy applied to create electrostaffs. Other metals in a position of resisting a lightsaber blade from each of these continuities include:

• Neuranium, which the statue Palpatine hid his lightsabers in was created of
• Songsteel, briefly canonized in the 2022 novel Shadow of the Sith as the content material an amulet owned by Rey’s father, Dathan, was manufactured out of
• Armorweave, a kevlar-esque solution that could be fashioned into apparel and undergarments

The Expanded Universe also introduced Vonduun crab armor, the spiked gear worn by the footsoldiers of the Yuuzhan Vong—which was described as obtaining a crystalline composition that created it capable of blocking blaster hearth and lightsaber bolts—as nicely as Ultrachrome, an historic steel with higher superconductive properties created use of in crafting starship armor that seems in Star Wars: The Aged Republic and is pointed out in the Mace Windu novel Shatterpoint.

Why Use Them More than Cortosis?

But if cortosis could each equally dissipate blaster hearth and disable a lightsaber for a period of time, why was it so at times utilised in comparison to other sources? Correctly, like we stated, in each the EU and the existing canon cortosis is an specifically scarce material. But even if you can find it, it is quite difficult to obtain into a lightsaber-resistant content material at scale. Cortosis essential watchful refining as it was also really brittle—making it hard and usually worthless to craft entire weapons or fits of armor out of it, compared to some factor like beskar or the additional standard armorweave.

Little blades, or helmets and gauntlets like these men and women utilized by the Stranger, had been the favored deployment of cortosis—individual pieces that could be applied for the material’s distinct qualities along with frequent armor. Even so, cortosis could also be utilised in a smithing technique acknowledged as cortosis-weave, the spot a mesh of fibers of cortosis ore could be bonded to armor and weaponry designed from other supplies. Despite the fact that this would help grant a lot more than sufficient electrical energy conduction to block a lightsaber blade, cortosis’ a single of a type capacity to short the weapon out would be reliant on the volume of cortosis by itself utilised in the weave—given its rarity and troubles to use, a lot a lot more normally cortosis-weave gear was only capable of resistance.
