How to Complete the Fire and Ice Exotic Mission and Get the Praxic Blade in Destiny 2
With the new Destiny 2 expansion, comes a new Exotic mission: Fire and Ice. This mission is part of the Renegades story campaign, where you’ll unlock some iconic gear and conclude the story. You’ll return to this mission later to upgrade the Exotic weapon it awards, so knowing how to complete it quickly and easily is essential. Here’s everything you need to know to master it.
Introduction to the Mission
Completing Fire and Ice involves navigating Ascendant Plane platforming challenges, battling Imperium Cabal forces, and tackling mechanic-heavy combat encounters. While my first run took over an hour, the second only took about fifteen minutes. Using this guide, you should achieve similar results. Your reward is the Praxic Blade Exotic Sword, unique to the Renegades expansion.
Finding the Entrance to the Vault
Your first objective is to enter the Praxic Vault, though the game provides no direct clue on where to go. From your spawn point, move straight ahead until you reach a zone with a large spherical cannon pointing toward the frozen sea.
Enter the Imperium base nestled within the ice wall — it’s the only entrance not blocked by an orange energy barrier. Inside, turn left and defeat the Imperium Colossus named Val Cal’Ric, Door Technician. Pick up the Imperium Door Codes he drops (a small pyramid item on the ground), then insert them into the console located in the middle of the room.
Beyond the gate, approach the Darkness totem in front of a door bound by Taken energy. This will spawn a horde of Taken enemies, including a yellow-bar Taken Ogre named Portal Keeper. Clear all the Taken enemies to make a portal appear in the energy barrier. Enter the portal and interact with the dark pyramidal item called the Imbalanced Octant. Collect it and find your way deeper into the complex.
Navigating the Ascendant Plane
To progress with the Octant, jump onto the lip around the pillar with floating Taken orbs. Drop through the far opening to descend — don’t fall straight down, as it will fatal. Move forward mid-fall to land on platforms ahead. From there, jump across platforms and stairs, following yellow lights as guidance.
After passing a small corridor with yellow lights, hang left and jump across gaps, continuing left across platforms until you reach a staircase leading to a vast chasm filled with large Taken blights. Keep going left, jump into a yellow-lit tower, and use platforms marked by melted sand to reach the top.
Next, jump across to the angled walls, beginning the “Platforming challenge, Renegades edition.” While it looks intimidating, it’s much simpler than it seems. You can skip much of it using the Eager Edge Sword to zip directly to the central broken staircase or sneak crouched underneath the angled walls.
Be cautious of push blocks that can launch you into the chasm below. At the far end, creep along a thin lip over the pit and follow it left. Jump to a snow-covered platform and then up to a second platform above. Hop onto a rock rising from the pit, cross to a Taken-corrupted tower, then back to the second level of angled walls.
Near the last gap, instead of heading toward the yellow-lit opening, turn right down a thin hallway. This hallway is a time-saver — it avoids a lethal push block trap near a yellow light. Navigate carefully, avoiding push blocks that will propel you off ledges permanently. At the hallway’s end, jump across to a small opening and proceed to the room with disappearing floors and open gates.
Here, follow a particular path before floors vanish beneath you: the farthest right gateway, the right gateway in the first center wall, the leftmost gateway, and finally the right-hand gateway. After reaching the hallway’s end, turn around.
Crouch-walk along the tops of previously crossed gates until you find a yellow-lit path in the right-hand wall. This leads to another enormous chasm filled with Taken blights, snipers, and a Taken Phalanx. Follow Taken bombs lighting vanishing blocks until you reach solid ground.
Find a rock jutting from the pit and jump onto it, navigating carefully to avoid the Phalanx’s shield blasts that can knock you into the pit. Jump down to a yellow-lit platform, enter the nearby tower, and jump until you reach the second-to-last platform. Look across the chasm to see three hanging platforms; jump across each and finally reach a far staircase.
Interact with the Darkness totem at the base of the staircase to reveal your path forward. Congratulations — you are now into the combat portion of Fire and Ice.
How to Balance the Scales
This combat section introduces Cleaving, along with Paired and Opposite Energy mechanics. The goal: fill four Light and Dark energy fields so they are balanced.
To fill the Light fields, you need Paired Energy; for Dark fields, Opposite Energy. Generating these energies involves defeating specific enemies:
- Taken occupy the right arena side, with two orange-bar Cleaved Taken Centurions beneath two energy fields.
- Cabal are on the left, with two orange-bar Cleaved Imperium Centurions below the other two fields.
Defeating Centurions awards either the Taken or Barant Energy Cleaved buff, determined by the faction you kill first.
Paired Energy: Kill two Centurions from the same faction (both Imperium or both Taken).
Opposite Energy: Kill one Taken Centurion, then one Imperium Centurion or vice versa.
Each energy type causes four throwable energy balls to drop. Throw two at their corresponding energy fields and two at the other, maintaining balance.
Repeat this until the energy fields become full spheres. Once one type is done, do the same for the other. If fields get out of balance, you’ll see a warning message and two yellow-bar Ultra enemies named Imbalanced Wardens will spawn. Defeat them to restart the process.
After filling both Light and Darkness fields into spheres, interact with the central structure to Calibrate Octant to Balance. Then collect the Balanced Octant and enter the portal back at the arena entrance. Use the Octant and Darkness totem to continue.
The world flips beyond the portal. After passing through it a third time, proceed to the final challenge.
Defeating the Disciple of Harrow
The final fight extends the mission’s previous mechanics. The Disciple has four health chunks, with major phase changes.
As you drain the first two chunks, the Disciple teleports to the back-left, summons a shield, and calls reinforcements. On his last health chunk, he becomes immune. You must fill two Darkness energy fields to drop his immunity.
This requires generating eight Opposite Energy and balancing it as before. The twist: Centurions only appear on one arena side at a time. Defeat the Centurion, then jump onto floating platforms above and use Darkness totems to swap enemy sides.
The first Darkness totem is on the arena’s left side — defeat that Centurion, jump up, and activate it. Timing is critical as the platforms vanish after a few seconds.
Fill both energy fields to full spheres, dropping the Disciple’s shield and allowing you to finish the fight.
You’ll be teleported to the center of the Praxic Vault, where the Praxic Blade awaits. Claim it — it comes as an Exotic Engram — then use it to cut your way out through dozens of enemies. The Blade is more than capable of handling the fight out.
Final Thoughts
And that’s how you complete the Fire and Ice Exotic mission and earn the Praxic Blade Exotic Sword in Destiny 2: Renegades. Although the mission seems complex initially, it becomes much faster and more manageable with practice.
You’ll need to get comfortable with Fire and Ice, as multiple completions are required for weapon upgrades. Fortunately, the mission is entertaining enough that replaying it isn’t a chore — a rare and welcome change.
