At the time a lightsaber is created, the crafter can choose one of the following modifications to apply to their lightsaber at no additional cost in time or credits.
A beckon call is a small communications device that links up with the slave circuits on a starship. When activated, the beckon call transmits a signal to the starship it is linked to, activating its autopilot programming and summoning the ship to the nearest safe spot close to the wielder. A beckon call functions only when connected to a starship with a slave circuit.
This modification reads the wielder’s biometric data when gripping the hilt. The lightsaber will only activate when it recognizes the owner’s biometric data. It may only store data for one user at a time.
This simple modification is usually added only to lightsabers whose wielders frequently throw the lightsaber as a ranged weapon. As a limited free action, the wielder can lock the blade in place; when doing so, this prevents the lightsaber from being accidentally deactivated when the weapon is jarred, such as during the impact of being thrown. A limited free action also unlocks the blade.
This lightsaber accessory is little more than a small compartment capable of holding a single object about the size of a comlink. Typically, this compartment in the weapon's hilt is used to store a useful item such as a comlink, hand-held holoprojector, or code cylinder.
A modification generally allowed only to high-ranking members of the Jedi Order, electrum detailing is usually a prestigious honor bestowed upon Jedi Masters as a sign of their rank and skill. A purely cosmetic accessory, electrum detail decorates the lightsaber handle with the rare metal electrum, giving it a distinctive gold color. Though electrum detail does not modify the mechanics of the lightsaber in any way, having a lightsaber with electrum detail grants a free reroll on Persuasion rolls against all targets familiar with the electrum detail tradition.
One end of this small cord of metal fibers attaches to the hilt of a lightsaber. The other end is attached to a piece of armor or a metal gauntlet, making it more difficult to disarm the wielder. When the wielder of a lightsaber with a fiber cord is disarmed, the disarming character cannot take the weapon (or call it to their hand, if using move object). The weapon is still considered "dropped" and the wielder must spend an action to pick it up, though it hangs by its fiber cord until the wielder does so.
This rare lightsaber modification removes the activation button from the lightsaber's exterior. To activate the lightsaber, the wielder must make a Force Use roll as a limited free action. If this check fails, the lightsaber does not activate. Typically this modification is used to ensure that untrained Force-users and those who have no sensitivity to The Force cannot effectively use the lightsaber.
This accessory is usually applied to pairs of lightsabers and intended for users who prefer to wield two lightsabers simultaneously. The creator of the lightsaber grafts a small, interlocking mechanism to the base of each lightsaber. As a limited free action, the hilts of the two lightsabers can be locked together, turning the weapon into a double weapon. They can be unlocked as a limited free action.
One of the most popular lightsaber accessories, the pressure grip is a staple of most Jedi who prefer simple, straightforward lightsaber construction. The pressure grip senses when the wielder's hand no longer grips it, deactivating the lightsaber immediately when it is dropped or disarmed.
A trapped grip requires the wielder to perform some limited free action (usually pressing down on a hidden sensor, twisting a nondescript knob, or some other mundane task) before activating the lightsaber safely. If the wielder does not perform this task at the time the weapon activates, the wielder takes 1d6 damage, and again at the start of his or her turn until the trap is deactivated. Deactivating the trap is a limited free action that is performed as a part of activating the weapon.
Favored by aquatic lightsaber-users, waterproof casing allows a lightsaber to function normally underwater. Without this modification, a lightsaber submerged in water shorts out and must be repaired (taking 1 minute of work) before it will activate.
Lightsaber wielders can use alternate crystals in the construction of their lightsabers, gaining certain benefits, depending on the crystal. Alternate crystals are rare, and finding one could be the focus of a small adventure or even a special prize for a Force user character completing a difficult quest. These crystals are not for sale on any market, and have no purchase value. Only Force users who specifically seek out to earn them can use one of these crystals for lightsaber creation.
Bondar crystals convert the energy of a lightsaber blade into a different form of energy. A lightsaber constructed with a bondar crystal deals stun damage instead of normal damage. Most training lightsabers are made with bondar crystals.
This crystal is found only on the remote Outer Rim world of Tatooine. Durindfire crystals give the lightsaber blades they focus a distinctive silver glow. Additionally, when you wield an attuned lightsaber with a durindfire crystal, the lightsaber emits a glow comparable to a Fusion Lantern, illuminating the area brightly.
Like the bondar crystal, a firkraan crystal absorbs the energy that creates a lightsaber blade and converts it into a different kind of energy, altering the effects of using the weapon. A lightsaber constructed with a firkraan crystal deals ion damage instead of normal damage, making lightsabers constructed with firkraan crystals more effective against droid enemies.
The discovery of the planet Ilum was a landmark event in the history of the Jedi Order. Up until its discovery, finding crystals to generate the full-strength blades that the Jedi Order required could be tedious and time-consuming. Jedi who undergo the ritual of lightsaber creation seek out the caves of Ilum, as their crystals are considered the highest quality. Ilum crystals are the standard used in lightsabers. Most often produce blue or green blades, but some may produce other colors.
Imperial Knights use synthetic crystals that produce a white blade. They have perfected the creation of these crystals to a point where they can mimic any other lightsaber crystal when created (except for the extremely rare crystals). When crafted, select a benefit from another crystal and permanently apply it to the Imperial Knight crystal.
The jenraux crystal widens the blade of a lightsaber. It also causes the blade to absorb kinetic energy, making it exceptionally effective at defending against incoming melee attacks. When you wield a lightsaber constructed with a jenraux crystal, you gain the effects of the deflection power against melee attacks.
Though a Kaiburr crystal is too large to be used in the construction of a lightsaber, when broken into shards the crystals can be used. The crystal amplifies its wielder’s senses. When you redirect a failed ranged attack against you, increase your Shooting die by one for the roll.
Found only on the planet Cerea, kasha crystals have great cultural significance to the Cerean people. During meditation sessions, Cereans use kasha crystals as a focus for their thoughts, sharpening their minds in the same way that a lightsaber crystal focuses an energy beam into a lightsaber blade. Kasha crystals help clear the mind and focus of the person using the crystal, blocking out distracting sounds, and other stimuli. When you wield a lightsaber with a kasha crystal, you gain the effects of the mind shield power.
The opila crystal increases the destructive power of the lightsaber against weak or unprotected targets, though it does little to allow the blade past most defenses. When you wield a lightsaber with an opila crystal, increase your damage die by 1 die type, but reduce the lightsaber’s AP by half.
A phond crystal reduces the cutting power of the lightsaber blade but solidifies the energy beam, making it more effective at negating energy attacks. When you wield a lightsaber with a phond crystal, you gain the effects of the negate energy power.
The rubat crystal causes the energy frequency of a lightsaber blade to fluctuate slightly, allowing the weapon to have a greater potential for damage. When you wield a lightsaber with a rubat crystal, you may reroll one damage die made with the lightsaber, keeping the better result.
A sigil crystal focuses the energy of a lightsaber blade with incredible efficiency, causing it to have a more devastating effect on a target. When you wield a lightsaber with a sigil crystal, you gain the benefits of the Elan Edge.
The solari crystal changes the width of a lightsaber blade, making it easier to intercept blaster bolts and other incoming ranged attacks. When you wield a lightsaber with a solari crystal, you gain the effects of the deflection power against ranged attacks.
Unstable crystals are usually the result of the machinery used to synthesize the crystal failing to accurately replicate the natural crystallization process. Unstable crystals create lightsabers with blades that crackle with energy at erratic intervals, sometimes causing sparks to fly from the blade or streaks of electrical energy to run from the hilt to the tip of the blade, and back. When you wield a lightsaber with an unstable crystal, the lightsaber deals an extra 1d6 on a raise. However, an attack that critically fails causes the lightsaber to deactivate, and it takes 3 actions to reactivate it.
The Ankarres Sapphire is a valuable gem that has passed through many hands over the years, including the hands of the Bounty Hunter 4-LOM around the time of the Battle of Yavin. Legend has it that the Ankarres Sapphire possesses incredible healing powers and that, when used as a lightsaber focusing crystal, it grants the wielder similar powers. Moreover, the legends say that only those who embody the light side of The Force can use the Ankarres Sapphire effectively.
If you wield a lightsaber with the Ankarres Sapphire and you have a no Dark Side Score, you get a +4 bonus on Healing checks or Force Use checks made to activate the vital transfer power.
The Ankarres Sapphire is thought to be unique, although it is possible that other such sapphires exist.
Found on Barab I, a Barab ingot is a special crystal found inside ore littering the planet's radiation-baked surface. Though the radiation on the surface of the planet makes it difficult to find these crystals, a few Jedi have managed to locate Barab ingots suitable for use as focusing crystals. However, the constant infusion of radiation on the surface of Barab I causes a Barab ingot to produce a lightsaber blade that burns like fire. A lightsaber constructed with a Barab ingot may cause flammable targets to catch fire.
If a target is hit, roll 1d6, on a 6 the target catches fire (very flammable targets catch fire on 4-6, volatile targets catch fire on 2-6). Targets that catch fire take an additional 3d6 damage. The fire continues to cause damage at the beginning of the victim’s turn. Immediately after, roll a d6, on a 1 the fire drops a die (to 2d6, then 1d6, then burns out), on a 6 the fire increases a die (maximum 3d6).
A character may make an Athletics roll to put the fire out as an action.
Found on the planet Dantooine, Dantari crystals originate in the eggs of the kinrath, creatures native to the planet. Dantari crystals were harvested in the ancient days of the Jedi, but once Ilum became a source of lightsaber crystals, few Jedi saw the need to deal with the deadly kinrath. Crystals harvested from kinrath eggs supposedly reflect the true disposition of the wielders. If you wield a lightsaber with a Dantari crystal and roll a raise on a Force Use roll made to activate a Force Power, you regain the power points spent on the Force Power.
A subject of both Jedi and Sith prophecy, the Heart of the Guardian is one of two legendary lightsaber crystals that surfaced in the days of the Old Republic. Though the origins of these crystals is unknown, it is likely that they were used in lightsabers of powerful Jedi as far back as the Great Hyperspace War. If you wield a lightsaber with the Heart of the Guardian, you gain a +2 bonus on attack rolls against targets that are also currently wielding an active lightsaber.
Krayt dragon pearls are found in the bellies of massive krayt dragons that roam Tatooine. Krayt dragon pearls come into being when existing gemstones deep in the desert sands of Tatooine are consumed by the krayt dragon; in the creature's belly, they are further compressed and refined until they reach a new level of clarity and beauty. Though obtaining one is usually a monumental task, a krayt dragon pearl can be refined into a lightsaber crystal of great potency. If you wield a lightsaber with a krayt dragon pearl, you gain a +2 bonus on damage rolls.
Grown by the Yuuzhan Vong as part of their biotechnology, lambent crystals are used as biological light sources. If you wield a lightsaber with a lambent crystal, you may target Yuuzhan Vong with Force Powers.
The companion crystal to the Heart of the Guardian, the Mantle of the Force is an ancient crystal that increases one's self-awareness while sharply attuning the wielder to the flow of The Force. If you wield a lightsaber with the Mantle of the Force, you gain a +2 bonus on Force Use checks made to activate Force Powers that have you as the sole target.
