Sith Artifacts
Concentration Talisman
Sith used these to focus their energy during long, intricate rites (those typically associated with harnessing vast amounts of Dark Side power). These devices have a major flaw. When at the completion of the task, the user of such a talisman succumbed to exhaustion. This prevented the use of these trinkets in battles. Jedi are also able to use these talismans to boost their concentration, aiding them in their long struggle with the Sith.
Ensnarement Talisman
This talisman operates in much the same way as one of concentration, especially to the Dark Side user. However, in the hands of a Light Jedi, it will gradually entrap the user into the Dark Side. Only the most powerful of Masters could use these Talisman’s without danger, leading to their widespread destruction, along with almost all the concentration talisman’s (which they greatly resembled), during the Fall of the Sith Empire, and later, at the end of the Sith War.
Healing Talisman
Many Sith disciples created talismans of healing to give their forces superiority in combat encounters. The devices endow the holder with the same benefits as the Jedi power Accelerate Healing with one difference - unlike Jedi healing, the recipient feels great pain as his wounds are healed. Use one at your peril.
Shield Talisman
One of the first Dark Side devices discovered and studied by the Jedi. This talisman protects the wearer from anything energy based (blasters etc.), and from Force attacks. Somewhat risky research suggests the talisman does this by taking the energy from the attack and using it as its own source of fuel. In order or remain viable however, the talisman requires an infusion of energy at least once per standard week. (It has been suggested that these Talisman’s have a certain vulnerability to lightsabers however.)
Translation Talisman
The tomes containing Sith lore and technique are written in their ancient language, which is virtually extinct since the fall of their empire. This talisman, created by a fallen Jedi, allows the wearer to read and speak the Sith tongue as if it were his native language.
Force Mask
These are very rare indeed. Using the Force sends ripple-waves throughout the galaxy, alerting anyone attuned to the Force (of course there is a question of proximity and how powerful the force-user is). The Sith learned techniques that could mask this natural occurrence, and created their Force Masks to cancel out the natural "waves" made when using the Force. This disguises the natural aura of a Sith Adept, making him virtually undetectable for Jedi using his natural emanations to track him.
Bracers of Najus
This ancient, Sith artifact was believed to have been hidden away beneath the Bleaks mountain range on Leritor. They were discovered by Profex Rynalla of the University of Sanbra, but she planned to use them for her own designs. The Bracers themselves were hidden in the wreckage of an ancient starship, where they had lain for millennia. The Bracers were originally created by the Sith Lord Najus, who hoped to use them to eliminate the Jedi Knights, and were unusually powerless if used against another Sith. Rynalla located the Bracers during her excavations, but the site was destroyed in a struggle and the Bracers were, once again, lost in the mountains.
Sith Amulets
In the long forgotten time when the Sith were a mighty race of magicians, a time when the Sith people were being driven to extinction by the Jedi Knights and the armies of the Galactic Republic. A time when Sith magic learned how to construct amulets to carry a message down through the centuries... a message from their reigning Dark Lord of the Sith. These artifacts were used to bring Exar Kun and Ulic Qel Droma into contact, thus ensuring that the Sith would live on forever.
Sith Amulets come in a variety of descriptions. Many are stones set into the back of a fingerless glove. This glove is further attached by a chain to a shoulder piece which straps to the shoulder and upper back and is further adorned with jewels.
These can be imbued with any number of powers as seen in the illustrated books. One type of crystal has been seen as a spirit catcher. Some Dark Lords used these to escape final death by putting their spirit inside these. They later appeared and corrupted unwitting pawns. These have also been used to trap one's enemies. Inside these crystals, the enemies are helpless, unable to use their Force abilities.
Exar Kun used an amulet to focus in rage into a blast of engery, at one point nearly killing him in the process as he was unable to control the effects and the shear amounts of energy flowing through him.
Amulets such as these have shown to possess the ability to create visual images of memories that the wielder has experienced.
Others were used as communications units between members of the Sith. They could pass the thoughts of two Sith over great distances and would not be dampened by comm blackouts.
Still others were amplifiers of Sith magic. They focus the dark side into great bursts. Aleema used one to remove the heart of a star and throw it at a Jedi fleet. This caused the star to go supernova. Recently, Draven has been using one of these to 'slip' in and out of the Force to use the Aing-Tii methods without losing his Sith abilities. One would think that if one of these crystals could amplify Force powers, one could also be used to limit Force powers.
Book of Sith Lore
Originally kept in the Great Galactic Museum on Coruscant, this book was stolen by Aleema and Satal Keto who used the Sith Magic detailed in the book to overthrow the Tetan Monarchy in the Empress Teta System.
Sith Scrolls
Only two such scrolls are known to have been recovered. These two scrolls, discovered by Exar Kun in the tomb of Freedon Nadd, are detailed navigational instructions on how to get to Korriban, the final resting place of the Dark Lords of the Sith. Its location has remained hidden for many centuries.
Sith Holocron
Many such information storage and retrieval devices exist in the galaxy. Each holocron provides a visual and vocal way to retrieve the information stored inside. The Sith Holocron can be differentiated from the Dark Holocron, used to store the information of other Dark Jedi, by its shape. The Sith Holocron is a translucent pyramid shape, small enough to fit in the palm on the hand. Each holocron has a gatekeeper, a Jedi who is in possession of the holocron and through whose image the stories of the holocron are told. A holocron is a powerful and informative tool which can only be activated by a person controlling the force.
Darkstaff
This ancient Sith artifact was believed to have been the cause of the disappearance of the planet Cularin, shortly after the Battle of Naboo.
Dark Armour
This Armor can be but isn't always alchemicly enhanced to make it lighter or harder etc. But it is always custom made for their wearers. Also almost no Armor ever gets found or passed down most Sith wear it to the grave or have it destroyed when they are.
Dark Combat Jump Suit
A heavily-paded jumpsuit that incorporates Cortosis weave, a material that deactivates any lightsaber that damages the wearer. This armour also grants its wearer increased protection from Projective and Receptive Telepathy used by other Force users, and increases the difficulty of a Force user sensing the wearer with Life Detection and Life Sense.
Dark Paded Battle Armour
This armour provides the wearer with increased defense against physical and energy damage. This armour is also imbued with Dark Side energy, granting the wearer increased defense against light side Force powers, or any Force power augmented by the light side.
Dark Heavy Battle Armour
This heavily-plated armour conveys incresed defense against physical and energy damage. It is imbued with Dark Side stealth to keep the wearer hidden against Life Detection and Life Sense. This armour also grants its wearer increased protection from Projective and Receptive Telepathy used by other Force users and increses the wearers physical strength.
Orbalisk Armor
Many Sith warriors chose to use orbalisks to create a kind of living armor which grew as the orbalisk reproduced. The individual orbalisks had to be removed, or the being would be covered and consumed by the orbalisk family. However, once a stable, symbiotic relationship was established, the orbalisk armor actually helped heal wounds which its host suffered.
Crystal Swords and Armour
In the most ancient of lightsabers, Adegan crystals were used as the focusing gems. It would follow that such crystals would be able to parry the lightsaber blades. Some of the Sith Empire's worlds existed in the Adegan sector before it was ravaged by the supernova which caused the Cron Drift. But, some of the ancient swords survived because they were buried with their owners in the Valley of the Sith Lords on Korriban. Draven has recently made a trek to his family tomb on Korriban and found a breastplate made of Adegan crystal. Although uncomfortable due to it being formed to another's chest dimensions, Draven wears it during ceremonies and lightsaber duels.
Sith Sword
A strong weapon first bestowed on Aleema and Satal Keto by Freedon Nadd. Not to be confused with the lightsaber. These dark and deadly weapons can withstand any punishment. Made indestructible by sorcery, their blades can even parry lightsabers! These weapons have survived the millenium with sharp edges and straight blades.
Sith Lanvarok
This wrist-worn weapon was used by the ancient Sith warriors. It was extremely complicated to use, and favors those users who are left-handed because of its configuration. The firing mechanism was mounted on the left side of the weapon, with the firing stud in a position to be pushed by the left thumb. The Sith lanvarok was originally developed as a hunting weapon, and fired a spread of thin, razor-edged disks at its target. It was time-consuming to reload, but deadly accurate at short range.
Massassi Lanvarok
A more primitive version of the Lanvarok was used by the Massassi warriors of Yavin 4, which resembled a polearm and required brute strength to throw the disks. After being used to launch the disk, the Massassi lanvarok could also be used as a slashing weapon.
