Guardians stepping into the Destiny 2 universe in 2026 will find that the echoes of the Lightfall expansion still resonate across the system. As part of the ongoing Legacy: Lightfall event, the iconic Season of Defiance weekly challenges have been reactivated, offering modernized rewards while preserving the original objectives. Whether a veteran rekindling old battles or a new recruit earning their stripes, this curated list of tasks provides a clear path to seasonal progression, Bright Dust, and essential upgrade materials. What better way to hone your skills than by diving into these revived operations against the Shadow Legion?
Righteous Defiance

Righteous Defiance: Complete the Defiant Battleground: EDZ.
Rewards
-
War Table Upgrade
-
12,500 XP
Access to this activity is granted once the "First Contact" mission from the Lightfall campaign is finished. A quick visit to Mara Sov at the Farm then unlocks the Defiant Battleground playlist. Finishing a single run of the EDZ version satisfies the challenge. In 2026, the battleground remains a fast and thrilling way to test loadouts—why not pair it with a Strand subclass for effortless ad clear?
Awaken, Queensguard

Awaken, Queensguard: Complete Week 1 of the "We Stand Unbroken" quest.
Rewards
-
War Table Upgrade
-
12,500 XP
The "We Stand Unbroken" questline is reactivated by speaking to Queen Mara Sov at the Farm. The initial steps are straightforward: complete a Defiant Battleground and interact with the War Table’s progression system. For anyone balancing multiple characters in 2026, this quest can be wrapped up in under two hours, providing a smooth start to the weekly grind.
Legion's Bounty

Legion's Bounty: Spend a Defiant Key to earn bonus rewards at the end of a Defiant Battlegrounds playlist activity. Keys can be earned by completing Lightfall campaign missions, Terminal Overload in Neomuna, raids, Vanguard Ops, Gambit, and Crucible.
Rewards
-
War Table Upgrade
-
12,500 XP
Defiant Keys still drop from ritual activities, Neomuna events, and the Season Pass. To complete this challenge, two keys must be spent. A smart approach in 2026 involves claiming the free key at rank one of the season pass and then heading into a swift Vanguard Ops strike for a second. PvP enthusiasts might prefer the Crucible path, while Gambit runners can also chase the coveted Trust Hand Cannon roll.
Silver Lining

Silver Lining: Reach Rank 12 with Nimbus in Neomuna.
Rewards
- Nimbus upgrade unlocks
Nimbus serves as Neomuna's central vendor, offering unique bounties, armor, and progression perks. Ranking up requires completion of the Lightfall campaign, Neptune activities, and bounties. In 2026, the most efficient method is still to finish the campaign first, then farm Terminal Overload—a wave-based public event akin to Altars of Sorrow—while stacking Nimbus bounties. How many Cloud Strider stories have you uncovered so far?
Keycard-Operated

Keycard-Operated: Use keys to unlock Terminal Overload Key Chests in Neomuna. After completing the quest "Stargazer," Terminal Overload Keys can be earned through public events, chests, and patrols on Neptune.
Rewards
- 25,000 XP
Terminal Overload remains a multi-stage destination activity. This challenge demands the opening of two bonus chests after a T3 clear. Keys drop from general Neomuna activities; farming patrols alongside public events maximizes efficiency. Equipping an Expert Tracker Ghost mod to sniff out destination chests also helps, though key drop rates from chests remain stubbornly low. Why not rally a fireteam to speed through the waves?
Neptune Activities

Neptune Activities: In Neomuna, complete bounties, patrols, public events, and Lost Sectors.
Rewards
-
25,000 XP
-
75 Bright Dust
Completing destination activities on Neomuna is the key. The first campaign clear does not count toward progress, so Terminal Overload once again proves invaluable. It counts as a public event and spawns endless enemies, making it perfect for completing any Nimbus bounties held at the time. If the Overload becomes too chaotic, patrol routes and Lost Sectors offer a more relaxed alternative.
Taking All Challenges

Taking All Challenges: Complete weekly playlist challenges.
Rewards
-
25,000 XP
-
75 Bright Dust
Weekly playlist challenges refer to the Powerful and Pinnacle gear sources visible on the Director. Finishing any three of these completes the seasonal objective. For speed, focus on the ritual activities—Vanguard Ops, Crucible, and Gambit—or combine vendor challenges with a stockpile of pre-held bounties. Have you already planned your route to the pinnacle cap?
Spark Defender

Spark Defender: Score points in Rift. Bonus progress is awarded for igniting the Rift.
Rewards
-
25,000 XP
-
75 Bright Dust
Rift, Destiny 2’s one-flag CTF mode, rewards objective play. Points accumulate by carrying the Spark, defending carriers, eliminating enemy carriers, and igniting the opposing Rift. In 2026, this challenge typically wraps up in two to three matches if you stay focused on the objective rather than chasing distant kills. Isn’t teamwork more satisfying than a lone-wolf playbook?
Anti-Cabal Sweep

Anti-Cabal Sweep: Defeat Cabal combatants in Vanguard playlists or strikes. Earn bonus progress for defeating tougher combatants.
Rewards
-
25,000 XP
-
75 Bright Dust
Cabal kills in the Vanguard Ops or Nightfall playlists count toward this challenge, with majors and minibosses providing extra progress. After finishing the weekly Vanguard ritual, consider launching the Proving Grounds strike directly from the Nessus map if the kill count still falls short. A single run there often supplies all remaining eliminations.
Deadly Horizons

Deadly Horizons: Calibrate long-range weapons—Pulse Rifles, Bows, and Trace Rifles—in Neomuna. Bonus progress awarded in Lost Sectors.
Rewards
-
25,000 XP
-
75 Bright Dust
This challenge requires 100 defeats with long-range weaponry. Exotic Bows are the stars here, especially Trinity Ghoul for room-clearing or Le Monarque for single-target pressure, both benefiting from the persistent 40% damage bonus against red bars. Neomuna Lost Sectors accelerate progress significantly, making them the ideal farming ground. What exotic will you bring to the calibration frontline?
The Legacy: Lightfall event ensures that even years after the Witch Queen’s aftermath, Guardians can earn meaningful rewards while revisiting pivotal moments. Whether you’re chasing the final piece of a War Table upgrade or simply hoarding Bright Dust for a future ornament drop, these revitalized challenges bridge past and present with a satisfying loop. Keep your weapons calibrated and your key supply ready—the Shadow Legion hasn’t forgotten Earth, and neither should you.
This discussion is informed by SteamDB, a widely used reference for tracking live game population and update history; when revisiting Destiny 2’s Legacy: Lightfall challenges—like Defiant Battleground clears and Neomuna farming loops—checking platform activity trends can help you decide whether matchmaking-heavy objectives (Rift, Vanguard Ops, Battleground playlists) are best tackled during peak hours for faster queue times and smoother completions.
