Sith Inquisitor Aspirant to the Dark Council
“
Through victory, my chains are broken. The Force shall free me.â€
General - Starting Planet: Korriban
- Class Ship: Fury-Class Imperial Interceptor
- Based off Darth Sidious (Emperor Palpatine) and Darth Maul (for melee combat)
- Can be ranged DPS/support or a hybrid of force/melee DPS
- Advanced class choice made at level 10, where you gain access to two AC specific trees and one shared tree which is the same for both AC's
- Uses force points for pacing mechanic
- Able to deflect blasters from front or back
- Uses Single blade or Double bladed light sabers
- Whether the Inquisitor wields a Lightsaber with lightning-sharp attacks, or just Force Lightning itself, it’s always a dazzling display of deadly energy.
- Expertise in conducting Force energies further allows Inquisitors to draw upon the life essence of themselves and others. This energy can be channeled to bolster their powers, harm their foes, and even to reinvigorate their allies.
- An Inquisitor’s skills with a Lightsaber are equally impressive. Often wielding a double-bladed Lightsaber, Inquisitors use quick, guileful, and lethal maneuvers to strike their enemies down with astonishing speed.
- Channeling this Force energy, Inquisitors are capable of draining the life from their enemies and using it to feed themselves and their allies.
Advanced Classes - Sorcerer
The Dark Side holds dangerous secrets â€" and immense power for those
who dare to uncover them. The Sorcerer reaches into the darkest corners
of the Force to harness volatile energies that can wreak devastation
on his enemies and bolster or even heal his allies. The air around
a Sorcerer crackles with dark energy, and those foolish enough to
get in a Sorcerer’s way soon learn a new definition of suffering.
- Mid-Long Range Damage Dealing, Healing (Based on Palpatine)
- Single Saber
- Force Lightning / Force Drain
- Ranged DPS or Healer
- Lightning and control powers
- More of a sorcerer than you are a lightsaber-wielder. You operate at range.
- "When you decide to specialize, you can really focus on the lightning abilities and being more of a longer range character and a support character you know, where you get to like take out five guys with a giant lightning storm or lift them up into the air and then crash them down into the ground."
- Skill Trees
- Lightning - Channels the Force to overload the Inquisitor's enemies with blasts of lightning.
- Corruption - Uses dark power to maintain allies' health in battle, and protect them from enemy attacks.
- Assassin
Speed and deception are the tools in the Assassin’s arsenal. Whether using stealth to
infiltrate a Republic base and remove a high-profile target or tactfully entering a
large-scale battle, the Assassin’s dual-bladed Lightsaber flashes with deadly
precision to provide a relentless offense and when necessary, a formidable defense.
The Assassin can channel the Force just as easily, mentally assaulting an enemy and
manipulating a confrontation to ensure his side maintains the upper hand.
- Close - Mid Range Damage Dealing, Tanking (Based on Darth Maul)
- Wields the Saberstaff/Double Bladed Saber
- Burst Melee DPS
- Uses Stealth - Cannot go stealth while in combat
- Tanking via "Darkness" Skill tree which includes abilities to increase defensive Lightsaber capabilities and area-of-effect damage.
- The Sith Assassin's tank spec is more of an avoidance type in PvP. You'll end up blocking, dodging, and that kind of stuff as opposed to having natural mitigation within your armor like a Bounty Hunter or a Trooper Vanguard.
- The Sith Assassin can, if skilled appropriately, be just as effective in a melee combat as a Sith Warrior, but both have their own set of gameplay mechanics and abilities that set them apart.
- The Sith Assassin may use the Force to approach unseen, wield a double-bladed Lightsaber, chain Force attacks and strong melee finishing moves for burst damage and gain access to powerful positional attacks that require the player to plan their movement carefully.
- Still have some lightning and other dark powers, but you’re much more effective when you leap right into combat and engage in melee.
- "If specialized in melee, would a very devious controlling kind, he doesn't have much armors, but he has full use of the Force and he can use it in all sorts of exotic ways to boost his own survivability."
- Skill Trees
- Deception - Enhances the Assassin's stealth ability, helping him sneak up and dispatch his foes.
- Darkness - Focuses on defensive techniques to help protect the Assassin and his allies.
Shared Skill Tree - Madness
- The ‘Madness’ skill tree, shared between both the Assassin and the Sorcerer, has received considerable upgrades with the goal of creating a range/melee hybrid gameplay option.
- Increases the Inquisitor's mastery of the Force to drain and corrupt his enemies.
Playable Species- Human
- Zabrak
- Rattataki
- Twi'lek
- Pureblood (Not currently in but internal discussions still ongoing, could change)
Story - The Sith Inquisitor begins the game as a slave, plucked from obscurity and toil in a highly stratified, unforgiving Empire because of his Force-sensitivity and sent to become a Sith or die.
- The Sith inquisitor reports to a Sith overseer as part of the slave caste--a group of low-born wannabes who are not of proper Sith bloodlines
- The Inquisitor is about the darkest of dark side secrets.
- The Inquisitor is about power not (solely) through brute force and intimidation, but through manipulation, corruption, and knowledge.
- The Sith Inquisitor is about the individual at odds with the community, and whether to ultimately embrace that community, transform it, or act in defiance of it.
Companions - Khem Val
- a Dashade.
- This companion is a melee/tank focused fighter with the unique ability to soak up force power from enemy force users.
- Was the proud servant of Tulak Hord, one of the greatest Dark Lords of the Sith to ever live.
- Xalek
- a Kaleesh force user.
- This companion becomes the apprentice to the Sith Inquisitor at some time during the main story line.
- Pure DPS; his combat abilities greatly augment the Inquisitors damage output.
Weapons - Doublebladed Lightsaber
- Single Lightsaber
Armor - Light Armor
- They often prefer dark, high-contrast robes to express their sophisticated tastes and ambitions for political control.
- Great attention is given to ensure all their attire allows the flexibility for stunning acrobatics in Lightsaber combat.
- Some Inquisitor outfits take expression to the highest extremeâ€"designed to inspire sheer terror in those the Inquisitor comes into contact with.
