Source: current SWTOR Flashpoint level chart ↗ · Master group encounters are designed for level 80, even where manual entry is possible earlier.

Mode and story notes: NO dedicated Story/Solo Flashpoint mode even though the level-50+ Imperial Tion story includes it. Manual Veteran from level 15; Veteran Group Finder from level 50; Master Group Finder at 80. The two-part story requires the quest Trouble in the Tion Hegemony, with Kaon before Lost Island.

  1. 01

    Accept the Imperial Tion story at level 50+

    On VAIKEN SPACEDOCK, open the station map and find LORD VELNINE in the SUPPLIES section. Accept TROUBLE IN THE TION HEGEMONY to follow the linked Kaon → Lost Island story. If you want only a repeatable run, the story quest is optional.

  2. 02

    Travel to the Ziost Shadow Mission Deck

    Use the fleet INTERFLEET TRANSPORT elevator and take the taxi to ZIOST SHADOW, or use its direct Quick Travel destination if available. On the capital ship head for the TION MISSION HANGARS on the SOUTH side of the Mission Deck.

  3. 03

    Talk to the Imperial mission contact

    For the full two-part story, speak to the story contact in the Tion hangar and follow the green-story-phase briefing. The briefing opens Kaon Under Siege as the first Flashpoint.

  4. 04

    Talk to EN-C7 by the entrance

    For a manual run, speak to EN-C7 in the Tion Mission Hangar, choose VETERAN MODE, and enter the nearby Flashpoint door. A pre-formed group should choose matching missions and difficulty.

  5. 05

    Do not mistake story access for Solo mode

    At level 50+ the two-part story is available, but the Flashpoint itself has NO dedicated Story/Solo difficulty or combat support droid. It requires a group in normal play.

  6. 06

    Activity Finder alternative

    At level 50–80, use ACTIVITY FINDER → GROUP → VETERAN FLASHPOINTS → FILTER → Kaon Under Siege. Manual entrance is preferable if following the narrative quest or introductory cutscenes.

02 · OBJECTIVE-BY-OBJECTIVE WALKTHROUGH

Where to go and what to click next

  1. 01

    Enter the Civilian Skyway

    Start in Kaon City and follow GET TO THE CIVILIAN SKYWAY. Look for a BLUE GLOWING DOOR and RIGHT-CLICK it. When grouped, each player may need to interact.

  2. 02

    Find the crash site

    Follow the city route and reach the CRASH SITE. Prioritize INFECTED MERCENARIES that grapple teammates; interrupt or stun them before they hold somebody for an extended period.

  3. 03

    Open the Security Gate

    At OPEN THE SECURITY GATE, find and RIGHT-CLICK the GLOWING BLUE GRATE/GATE object. A locked gate does not open by killing enemies alone.

  4. 04

    Defend against the infected swarm

    Start the DELAYED CHARGE DETONATOR DEFENSE by RIGHT-CLICKING THE BLUE BOX. RIGHT-CLICK the nearby TURRET to mount it, then point it at the rakghouls; the turret auto-fires in its facing direction.

  5. 05

    Talk to Major Byzal

    After the defense, follow the path to MAJOR BYZAL and complete the conversation. If in a group, everyone may need to trigger the interaction to progress.

  6. 06

    Get to the Military Checkpoint

    Follow the next city route until GET TO THE MILITARY CHECKPOINT. Move through the required passages rather than trying to cross inaccessible streets.

  7. 07

    Detonate the Explosives

    Locate the mission-highlighted explosives/control at the checkpoint and RIGHT-CLICK to DETONATE THE EXPLOSIVES. This is separate from the first detonator-defense event.

  8. 08

    Reach the Rendezvous Point

    Continue through the transit district to GET TO THE RENDEZVOUS POINT. Optional containment beacons and the KR-82 Expulser belong to a bonus quest.

  9. 09

    Defeat the Rakghoul Behemoth

    Bring the large red Behemoth beside a nearby IGNITABLE CANISTER; RIGHT-CLICK the canister while the boss is close enough to set it on fire and increase damage.

  10. 10

    Get to the Spaceport

    Follow GET TO THE SPACEPORT. Clear or safely bypass infected groups and reach the final super-soldier arena.

  11. 11

    Defeat the three Rakghoul Super-Soldiers

    Fight COMMANDER LK'GRAAGTH, CHAK'AGHAKH and G'KLARG. Coordinate focus fire; a common group tactic is focusing the Commander first.

  12. 12

    Search for survivors

    After the final enemies die, the objective is SEARCH FOR SURVIVORS IN THE SPACEPORT. Follow the marker and complete the final interaction/conversation before leaving, then return to the Tion hangar for the Lost Island handoff.

Optional activities: QUARANTINE BREACH unlocks KR-82 Expulser in Veteran and Master: defeat 25 + 25 hostile contacts → activate SIX containment beacons → defeat KR-82. The secret MIDNIGHT RAKGHOUL appears ONLY during the Rakghoul event; bring plague vaccines if choosing that separate challenge.

03 · COMBAT TROUBLESHOOTING

Boss mechanics without guessing

These descriptions cover the relevant objective, visual warning, controls and known failure points. Optional bosses are labeled and do not block the mandatory story.

ENCOUNTER 01 / 04

Delayed Charge Detonator Defense

Where: Kaon City, after the first security gate.

  1. 01

    Activate the blue detonator box

    RIGHT-CLICK the glowing blue box to initiate the event.

  2. 02

    Mount the turret

    RIGHT-CLICK the newly available turret. The gun may not be highlighted even when usable.

  3. 03

    Rotate toward the waves

    The turret automatically fires toward its current aim. Turn to keep rakghouls inside its field of fire.

  4. 04

    Dismount when finished

    Right-click the turret buff icon if you need to leave the mounted gun.

Stuck here? No turret action bar? The gun auto-fires when aimed. Do not assume the event has bugged because no separate fire button appears.

ENCOUNTER 02 / 04

Rakghoul Behemoth

Where: Rendezvous area before the Spaceport route.

  1. 01

    Position near the canister

    Bring the Behemoth close to an ignitable fuel canister before using it.

  2. 02

    Click the canister

    RIGHT-CLICK the canister to set the boss on fire and increase the damage it takes.

  3. 03

    Kite the frenzy

    When it enters a frenzy and chases a character, move away until the aggressive period ends.

Stuck here? Slow damage on Behemoth is often because the group never ignited a canister. Move it close to one and interact.

ENCOUNTER 03 / 04

KR-82 Expulser (optional bonus)

Where: Near the post-Behemoth area, unlocked by Quarantine Breach.

  1. 01

    Finish the bonus counters

    QUARANTINE BREACH: defeat 25 contacts, 25 more, then ACTIVATE SIX CONTAINMENT BEACONS.

  2. 02

    Use glowing beacons

    Look for blue glowing beacons across the city; some double as defensive turrets.

  3. 03

    Destroy Emergency Response Droids

    Focus the smaller droids when they spawn during the KR-82 fight.

Stuck here? KR-82 is optional and requires the bonus; it does not replace the three mandatory super-soldiers.

ENCOUNTER 04 / 04

Rakghoul Super-Soldiers: Lk'graagth, Chak'aghakh and G'klarg

Where: Spaceport final encounter.

  1. 01

    Identify all three named enemies

    COMMANDER LK'GRAAGTH fights alongside CHAK'AGHAKH and G'KLARG.

  2. 02

    Coordinate a focus target

    A common tactic is to defeat the Commander first, reducing enemy pressure one at a time.

  3. 03

    Finish the survivor objective

    After the trio dies, follow SEARCH FOR SURVIVORS IN THE SPACEPORT; do not exit until it advances.

Stuck here? If the Flashpoint tracker still shows survivors, the boss fight alone was not its last objective.

04 · FIND A QUICK FIX

Why the quest is not progressing

Where is the Imperial entrance?

On Fleet, find LORD VELNINE in SUPPLIES for the story, then INTERFLEET TRANSPORT → ZIOST SHADOW → southern TION MISSION HANGARS → EN-C7.

Reference and original discussion ↗

I am on the story, why can I not enter Solo mode?

There is no dedicated solo version. The level-50+ story uses the group Veteran Flashpoint and the separate Trouble in the Tion Hegemony mission.

Reference and original discussion ↗

I can't open the first city gate.

Click the BLUE GLOWING DOOR for Civilian Skyway, then the BLUE SECURITY GATE/GRATE for Open the Security Gate. All party members may need to click.

Reference and original discussion ↗

Where do I go after the Spaceport fight?

Follow SEARCH FOR SURVIVORS IN THE SPACEPORT; finish the interaction and return to the Ziost Shadow story contact for the Lost Island continuation.
