I am a regular Destiny 2 player, and I still keep a soft spot for Season of the Haunted. Writing in 2026, I have to be honest: the Week 4 challenge reset from Season 17 is not a live event anymore. The live calendar has rolled through many resets since then, and the sandbox has moved on. So I treat the old Week 4 checklist as a time capsule... a very useful one. It shows how the Season of the Haunted loop asked players to bounce between the Derelict Leviathan, the Nightfall playlist, Gambit, and the Crucible. The challenges line up like a pit crew, each one waving me toward a different activity. I can almost hear the Leviathan’s hull ticking as it cools.

The story beat is still the headline for me. Week 4 continued the Bound in Sorrow questline, with Zavala confronting his Nightmare once more. I returned to the area of the Derelict Leviathan that the previous week had opened up, and the place still felt like it was watching me. The ship has a way of making every corridor feel personal. That is a mouthful, I know, but it is also why Season of the Haunted stuck with so many players.

There were nine new challenges in the fourth week’s set, and they offered more XP, Bright Dust, and Figments of Darkness. I like a checklist that gives me a reason to touch every corner of the game, and this one did exactly that. Here is the board as I remember it, with the rewards and tasks laid out cleanly:

Challenge Type Task Reward
Sorrow Bound IV Story Complete Bound in Sorrow IV and defeat Cabal Centurions throughout the system Challenger XP+
Crematory Fist Leviathan combat Defeat combatants with melee abilities on the Derelict Leviathan; Solar melee or Nightmare melee kills grant extra progress Challenger XP+
Burning Shame Sever activity Complete Sever - Shame using only a Solar subclass and Solar, Kinetic, or Stasis weapons Figments of Darkness and Challenger XP+
Shape of Nightmares I Crafting Extract weapon elements from a Haunted weapon with a Deepsight mod Challenger XP+
Mod Collector Artifact Unlock 12 artifact mods Challenger XP++ and Bright Dust
Precision Calibration Weapon calibration Land precision final blows with Linear Fusion Rifles, Sniper Rifles, and Scout Rifles; bonus progress against Guardians Challenger XP+ and Bright Dust
High-Value Hunter Gambit Defeat powerful combatants in Gambit; bonus progress for high-value targets Challenger XP++ and Bright Dust
Flourish of Power Crucible Defeat Guardians in the Mayhem playlist with Super abilities Challenger XP+ and Bright Dust
Darkest Nightfall Nightfall Complete any Nightfall strike on Hero difficulty or higher Nightfall weapon, Challenger XP+, and Bright Dust

The reference text also flags Trials of Osiris returning that weekend, with the Forgiveness Sidearm and Burden of Guilt Fusion Rifle up for grabs. Forgiveness is a two-burst Arc energy sidearm, and Burden of Guilt is a Stasis fusion rifle. Adept versions could only come from going flawless on a Trials card and visiting the Lighthouse. That is the kind of detail I like to keep straight, because Trials loot has a way of making players forget their other weekly chores.

Mayhem is the hyperactive cousin of the Crucible, and in Season of the Haunted it made its first appearance during this week. I would prioritize the Mayhem challenge before the fifth week arrived. It is a limited activity, and limited activities have a habit of tapping me on the shoulder and then vanishing. The Nightfall also waits with folded arms. Horror’s Least was the weekly Nightfall weapon, a Rapid-Fire pulse rifle that still had value in PvP. There was no Grandmaster version for an adept drop at that point, so I would not chase a phantom. I would just enjoy the gun for what it was.

If I were running this checklist today, I would start with the story and Sever - Shame because they anchor the week. Then I would clean up the easy artifact and Deepsight tasks. After that, I would move into the playlist chores: Gambit for High-Value Hunter, Mayhem for Flourish of Power, and a Hero Nightfall for Darkest Nightfall. Precision Calibration would come last, because precision final blows in a busy playlist can be a test of patience. I would not sleep on Horror’s Least, either. A good pulse rifle can quietly become a favorite.

For a 2026 reader, the value here is historical and archival. This is not a live service alarm; it is a player’s notebook from a very specific moment in Destiny 2. The challenges show how Season of the Haunted mixed story, ritual playlists, and weapon crafting into one weekly loop. I would not blame you for feeling nostalgic. I still do. The Leviathan may be old news now, but the checklist still reads like a map of a season that asked players to look inward and face a few nightmares.

Final thought: the fourth week was busy, but it was not cruel. It gave Guardians a clear route through XP, Bright Dust, and Figments, with a Trials weekend and a Nightfall weapon as the shiny extras. In 2026, I can only revisit it with hindsight, but the structure still holds up. Do not let the shiny object distract you from the story... and do not forget to check the board before the reset.
