How to Get the Praxic Blade Lightsaber in Destiny 2 – Full Exotic Guide
How to Get Praxic Blade Lightsaber in Destiny 2 — Complete Exotic Guide (Quest, Puzzle, Boss & All Catalysts)
Praxic Blade is a new exotic sword in Destiny 2 added with the Renegades DLC. Players instantly nicknamed it the “Lightsaber” thanks to its look and fluid animations, but it’s more than just a visual reference. This exotic is unique because it offers three distinct combat styles in a single weapon, each better suited for different activities and playstyles. In this guide, we’ll go through how to get the Praxic Blade, how to complete the Fire and Ice mission, solve the puzzle, defeat the Disciple of Harrow, and unlock all currently available catalysts.
If you don’t feel like dealing with a long exotic mission, tricky platforming and hidden oddities, you can always let Dving’s pro players unlock Praxic Blade and its catalysts for you, while you focus on the parts of Destiny 2 you actually enjoy.
How to Start the Praxic Blade Quest
To start the Praxic Blade quest, you first need to finish the Renegades campaign and move into the post-campaign progression.
The quest becomes available around step 33 of 45 in the post-campaign chain.
At this point, you’ll receive an objective to visit the Praxic Temple with Aunor.
Following this objective launches the exotic mission “Fire and Ice”.
Unlike simpler exotic quests, Fire and Ice feels much closer to a mini-dungeon: it has long platforming sections, puzzle mechanics, and a boss that reuses the puzzle rules. You can technically complete it solo, but the difficulty and length make it far more comfortable with at least one teammate.
Destiny 2 Praxic Blade Quest Walkthrough (Fire and Ice)
The Fire and Ice mission is split between combat, platforming, and puzzle arenas. Below is a concise walkthrough, staying close to the original flow but with clearer structure.
Enter the Imperium Base
Push through the opening Cabal and Taken enemies until you find the Door Technician.Kill him to obtain door codes.
Use the console to open the main gate.
In the next room, clear waves of Taken until a Portal Keeper appears.
Defeat the Portal Keeper to open a portal to another dimension.
Pick Up the Imbalanced Octant
Step through the portal into a new dimension.On a pedestal ahead, you’ll find a triangular object – the Imbalanced Octant. Pick it up.
Move to the spire in the center of the room. There’s a hole at the top you must drop into.
As you fall and land inside the spire, follow the broken platforms forward, then left, to reach an open area filled with floating spheres and platforms.
Wall Traps and Vertical Climb
In the open area you’ll see a large wall with push-traps that try to knock you into the abyss.Move along the narrow catwalk, timing your movement between the traps.
At the end, jump around the wall to the left onto a small platform.
Look to the right, climb the broken pillar, and continue upward.
On the second level, you’ll encounter more traps, this time Taken explosions along a catwalk. Go almost to the end and then turn right into another passage.
Disappearing Blocks Introduction
Here you see blocks marked with four-pointed stars. These disappear when touched.The first star block is directly across the room – do not step on it.
Instead, turn right before it and follow the route with disappearing blocks in the side room.
These platforms lead you to a narrow pathway and toward the next section.
Disappearing Maze
You now enter a maze where much of the floor disappears after you step on it.The key here is to keep moving and quickly identify doorways that actually lead somewhere.
Some passages end abruptly, so don’t rush blindly.
Eventually you’ll reach a staircase leading up to a door.
From there, you must jump across broken pillars suspended above disappearing blocks. Falling forces you to repeat the earlier part, so take your time with jumps.
Final Jumping Gauntlet
The last platforming section combines disappearing blocks, Taken blights and Taken snipers.Every platform you step on eventually vanishes, so you must move quickly.
After the obstacle course, you reach solid ground.
Turn left, climb several small ledges, then reach a large platform. Below it is a stone tower. Drop down onto its foundation and head inside.
Place the Imbalanced Octant
Inside the tower, climb most of the way up, but stop at a platform just below the very top.Look out the window and you’ll see inverted pillars in front of you.
Jump onto them; at the end you’ll find a device where you can place the Imbalanced Octant.
After placing it, go back up the stairs and through the portal to reach the puzzle arena.
From here, you enter the area where the main Praxic Blade puzzle takes place – the same mechanics will later be reused in the boss fight.
Praxic Blade Puzzle Solution
After the portal, you arrive in an arena with a large white orb floating overhead and four smaller spheres (two white, two black) around the room. The goal is to balance energy between these spheres by using orbs dropped from specific enemies.
Kill the Cleaved Centurions
There are two types of special enemies:
Cleaved Imperium Centurion
Cleaved Taken Centurion
The order in which you kill them determines which orb you get:
Kill Order | Orb Type |
|---|---|
Imperium → Taken | Black Orb |
Imperium → Imperium | White Orb |
Taken → Imperium | White Orb |
Taken → Taken | Black Orb |
Either color is fine, as you’ll need both white and black at some point. Focus on staying alive and controlling the arena while picking up the orbs.
Balance the Spheres
Hovering around the arena are two white spheres and two black spheres.
Your objective is to:
Throw white orbs into white spheres.
Throw black orbs into black spheres.
However, there is an important limitation:
If you keep feeding a single sphere with too many orbs compared to its pair, it will overload, forcing you to restart the process.
Never allow more than two orbs difference between two spheres of the same color.
White spheres are linked between themselves, and black spheres are linked between themselves.
Throwing an orb of the wrong color at a sphere simply does nothing, it doesn’t break anything.
Distribute the orbs evenly between matching spheres until they are fully charged. When you’re done, go to the center and interact with the object to calibrate the Octant. This opens a portal near the entrance.
Go through the portal, and the world flips upside down. From here, jump across to the doorway opposite the portal – this starts the Disciple of Harrow boss encounter.
Disciple of Harrow Boss Guide
The Disciple of Harrow fight isn’t mechanically brutal in terms of raw damage, but the puzzle integration can make it drag on if you don’t understand what to do. The boss has four HP bars:
Drain the First Bar
Simply deal damage until you deplete the first health segment.
Destroy the Cabal Shields
After the first bar is gone, the boss becomes shielded.
Several shield generators appear in the arena. Destroy them to drop his shield and allow damage to the second HP bar.
Deplete the second bar, repeat the process for the third bar.
Final Phase — Balancing the Spheres Again
In the last phase, you’ll notice two spheres floating above the arena and a triangle in the center of the room.
This repeats the energy-balancing mechanic from the earlier puzzle.
Kill Cleaved enemies to gain the Energy Cleaved buff and spawn white/black orbs.
Interact with the center triangle to switch which type of Cleaved enemies spawn (Imperium or Taken), giving you access to different orbs.
Fill both spheres with the correct orbs, again keeping them balanced and avoiding overload.
When both spheres are properly filled, the boss becomes vulnerable one last time. Finish him off to complete the encounter.
Once he dies, you’re teleported into the Praxic Vault.
Interact with the sword stand in the middle to receive Praxic Blade.
The color of the blade is randomized on first pickup. You can later unlock more colors by completing certain activities.
After picking up the sword, you are taken into a practice room to test your new weapon before the mission completes.
How to Get Praxic Blade Catalysts
Praxic Blade is heavily customization-focused. You can:
change blade color,
swap blade focuses,
adjust stance,
change power cores,
and, most importantly, unlock multiple catalysts.
At the moment, there are three available catalysts, with a fourth one locked behind an unreleased dungeon:
Echoing Blade — improves the thrown blade, allowing it to damage more targets.
Hyperblade — grants a powerful amplification after reflecting shots, boosting your next swing distance.
Upper Hand — a Star Wars-themed effect that increases thrown and reflected damage while you’re on higher ground.
The last catalyst, Energy Conduit, will arrive later with the dungeon.
Echoing Blade Catalyst (All Oddities)
To unlock Echoing Blade, you must destroy 7 “oddities” during the Fire and Ice mission. Oddities appear as Taken spheres in hidden or hard-to-reach spots.
All of them must be destroyed in a single mission run.
Below is a summarized path, keeping the logic of the original locations:
1st Oddity
Near the spire where you drop down after the first portal.
Before falling all the way down, look to the right for a large platform.
Land there, follow the lit ledges to a pothole with a Special ammo chest.
To the right of the chest is a narrow path with disappearing star blocks.
Touch them all in quick succession so they disappear, return to the chest, and use a Heavy throw from Praxic Blade to hit the Oddity (a Taken sphere) in the distance.
2nd Oddity
Go back to the spire and this time drop to the bottom.
Proceed as normal until just before entering the large open area.
On your right, there is another star-marked disappearing wall.
Touch it and follow the path beyond to find the second Oddity.
3rd Oddity
Continue into the jump puzzle with push-traps.
When you climb onto the broken pillar to reach the second floor of traps, don’t go toward them.
Instead, turn right from the catwalk and jump forward toward a barely visible ledge.
Follow a series of small ledges upward; the third Oddity is hidden behind a corner at the top.
4th Oddity
Reach the first room with disappearing blocks where you learn the mechanic.
Use the blocks to get to the narrow pathway as usual.
Before dropping down into the maze, look around the upper level.
There is a small tricky ledge off to the side – jump onto it.
Move along it until you can blade-dash forward with Praxic Blade into a small room with a disappearing floor.
Step on it and drop down. Two disappearing blocks are in this room; the one sticking out at an angle hides the fourth Oddity behind it.
5th Oddity
Proceed through the disappearing floor maze and start the long jump section.
Aim for the second catwalk and then drop onto a side ledge to its right.
Look up to see another ledge you can jump to.
Turn left and walk toward an inverted spire that’s split in two.
Another disappearing wall sits above you; touch it and jump up into a hidden room with Special ammo and the fifth Oddity visible through a window.
6th Oddity
Reach the room with disappearing blocks, Taken blights, and snipers.
Clear the course normally until you hit the solid ground at the end.
Turn left and jump onto a rocky platform with two Taken traps.
Instead of turning left toward the inverted tower, move straight toward the cliff edge.
Drop into a small pothole below; the sixth Oddity is here. It can be awkward to hit, so aim carefully.
7th Oddity
From the previous area, work your way upward to the very top.
You’ll see a high tower above.
Climb into the highest accessible platform.
Look up and locate a small opening overhead.
Throw your Praxic Blade into that hole to destroy the seventh Oddity.
After all 7 oddities are destroyed:
Finish the mission normally.
In the Praxic Vault, look for golden cases on the floor in front of the sword stand.
Interact with them to claim the Echoing Blade catalyst.
Hyperblade and Upper Hand Catalysts
These two catalysts are linked and can be obtained in a single run if you follow the steps correctly.
Step 1: Kill the Two Imbalanced Wardens
At the start of the Fire and Ice mission:
Turn away from the main door and explore the side areas.
The first Imbalanced Warden is opposite the door you’re supposed to enter.
The second Imbalanced Warden is hidden to the left of that entrance, down an arched tunnel.
After you kill both, you should see the message:
“Remnants of Darkness persist through time.”
This confirms you’ve triggered the condition.
Step 2: Overload Every Sphere in the Energy Puzzle Arena (Hyperblade)
When you reach the energy puzzle arena with the four spheres:
Instead of balancing them correctly, your goal is to overload every sphere.
Pick up the orbs and repeatedly throw them into the spheres until each overloads.
Every time you do this cycle, an Imbalanced Warden spawns – kill it.
Repeat the process four times.
After the fourth cycle, a Catalyst of Imbalance appears – a giant Taken Ogre.
Defeat it to complete the requirement for the Hyperblade catalyst.
You’ll receive Hyperblade in the Praxic Vault at the end of the mission.
Step 3: Return to the Start for Upper Hand
After flipping the arena and before starting the boss fight:
Backtrack all the way to the beginning of the mission, where you fought the two initial Imbalanced Wardens.
There you’ll find two oddities that must be destroyed using Praxic Blade.
Destroy both of them; this spawns two additional white spheres beneath the arena.
Return to the energy arena, fill those extra white spheres evenly (do not overload them), and then finish the mission and kill the boss.
Once you reach the Praxic Vault, you will see the Upper Hand catalyst waiting alongside the other rewards.
Conclusion
Praxic Blade is one of Destiny 2’s standout exotics: a fully customizable “Lightsaber” with three combat styles, a complex acquisition mission, and multiple catalysts that dramatically alter its behavior. By following this guide, you can:
Start and complete the Fire and Ice mission
Solve the Praxic Blade puzzle and defeat Disciple of Harrow
Destroy all seven oddities for Echoing Blade
Unlock Hyperblade and Upper Hand in a single optimized run
Once the fourth catalyst, Energy Conduit, becomes available with the dungeon, it will add even more depth to this already flexible exotic.
F.A.Q.
How do I obtain the Praxic Blade exotic in Destiny 2?
You must complete the exotic mission Fire and Ice, which unlocks during the Renegades post-campaign content.
How do I get the Praxic Blade quest?
Progress through the Renegades storyline until around step 33, when the quest instructs you to visit the Praxic Temple with Aunor. That leads into Fire and Ice.
Can you get Praxic Blade in Renegades?
Yes. You need to own the Renegades DLC and complete the post-campaign exotic quest chain.
Is it possible to get Praxic Blade solo?
It is possible, but very difficult and often frustrating due to long platforming and puzzle mechanics. It’s much easier with at least one fireteam member.
Which DLC includes Praxic Blade?
Praxic Blade is part of the Renegades expansion.
Can I get all four Praxic Blade catalysts now?
No. Right now, you can only obtain three catalysts (Echoing Blade, Hyperblade, Upper Hand), all found within the Fire and Ice mission. The fourth, Energy Conduit, will be available only when the related dungeon goes live.
Which catalyst is the best for Praxic Blade?
Echoing Blade is excellent for PvE, especially for hitting multiple targets at range.
Hyperblade shines when you actively reflect shots and capitalize on the movement buff.
Upper Hand is solid in any mode, as the bonus damage from higher ground works in both PvE and PvP.
