Fire and Ice is one of the most memorable missions in Destiny 2: Renegades. It mixes slow, methodical platforming with a multi-phase combat puzzle and finishes with a boss encounter that demands both damage output and mechanical awareness. This walkthrough is designed for players who want a clean, repeatable route through the mission—no wasted time, no guesswork.
Mission Flow Overview
You’ll move through the mission in a fixed structure:
- Reach the Praxic Vault
- Navigate the Ascendant Plane platforming route
- Balance Light and Darkness in the Calibrate the Scales arena
- Fight and defeat the Disciple of Harrow
- Claim the Praxic Blade to complete the sequence
Everything from here explains how to handle each section efficiently.
Entering the Vault — Early Combat & Setup
You begin in an open snowy zone with scattered Imperium Cabal patrols and Taken energy anomalies. Push forward through the base until you reach the interior lock chamber. Clearing enemies will eventually allow you to activate the pyramid mechanism and shift into the Ascendant Plane version of the vault.
This is a one-way step. Make sure you grab the dark-shaped artifact that appears after your initial clear—without it, you won’t progress deeper.
Ascendant Plane Route — Navigating Safely
This is the mission’s longest non-combat section. It’s less about speed and more about reading the environment correctly.
Key navigation tips
- Look for dark walkways, suspended beams, and angled wall-plates.
- When unsure where to go, follow dim yellow-white lighting along surfaces—those paths usually indicate the correct direction.
- Push-blocks exist in several walls and floors. If you see metal panels shifting, stop and time your movement.
- Expect disappearing walkways—you may need to move decisively rather than slowly.
After threading through wall-gaps, blight-covered pits, and high platform runs, you’ll reach the central Praxic Vault entrance. Interacting with the pyramid construct opens the portal to the first real encounter.
Balancing Fire and Ice — Combat Mechanic Breakdown
You now enter a large ritual room with four blights, arranged two-by-two. The goal is to fill each blight with the correct energy type and keep both sides progressing evenly.
Notation for clarity:
| Energy Type | How to Generate It | Color Result |
|---|---|---|
| Paired Energy | Defeat two of the same Cleaved enemy in a row | White |
| Opposite Energy | Defeat one Cabal + one Taken (any order) | Black |
Each correct pair generates throwable energy orbs. These must be tossed into their matching blight. Make sure both blights of a color are upgraded at the same pace—dramatic imbalance will reset progress and spawn additional elites to punish you.
Clean rotation approach
- Choose either Paired or Opposite first—finish both blights of that type before swapping.
- Throw two orbs into one blight, two into its twin.
- Keep them within two growth tiers of one another.
- Once all four blights reach full form, return to center and calibrate the octant.
When the ritual completes, a portal opens. Step through to face the mission’s final challenge.
Final Fight — The Disciple of Harrow
The boss arena is a wide Cabal structure with minimal cover and constant adds. This fight has two layers:
Phase 1 — Pure Damage
The Disciple of Harrow is vulnerable from the start. The boss wields heavy Cabal weaponry and will phase backward twice as its health reaches new thresholds. Adds spawn alongside it, but no puzzles are required until the last segment.
Unload your supers and heavies early to shorten these rotations, as prolonged add presence becomes the real danger.
Phase 2 — Fire & Ice Mechanic Returns
During the final quarter of its health, the Disciple becomes immune. Two blights appear—this is your final Balance the Scales checkpoint.
Key difference from earlier: enemy type alternation is controlled by platform-activated totems rather than fixed spawns.
- Kill a Cleaved elite to generate one energy condition
- Jump to upper floating platforms and activate totem pillars to switch enemy faction side
- Create Opposite or Paired energy as needed to power each blight
- Keep progress even and avoid overfeeding a single node
Once both blights reach full growth, immunity breaks. This is your finishing window—burst hard and end the fight before another shield cycle begins.
Mission Reward — Praxic Blade
Completing the encounter transports you into the Praxic Temple, where the Exotic sword awaits. It’s fast, visually striking, and designed for aggressive close-quarters combat. Future upgrades and color attunements unlock after the story climax, so expect to revisit this mission later for optimization.
