Discover why Destiny 2’s unsunset 21% Delirium remains a top-tier add-clear weapon with effortless acquisition
The Unsetting Revolution: Bringing Back Classic Arsenal
Destiny 2’s The Final Shape expansion marked a pivotal moment for veteran Guardians by reversing the controversial sunsetting policy that had previously rendered beloved weapons obsolete. This strategic shift allows players to infuse their favorite power-capped arsenal up to current Light Levels, breathing new life into classic gear that had been shelved for years.
The community had passionately advocated for this restoration for an extended period, though the decision later faced criticism that prompted Destiny 2’s senior game designer to justify the implementation. This policy adjustment represents Bungie’s acknowledgment of player attachment to their carefully curated weapon collections and the importance of build diversity.
While most unsunset weapons haven’t dramatically shifted the PvE meta due to being outpaced by newer alternatives, 21% Delirium stands as a notable exception. This Arc machine gun maintains its effectiveness so well that even seasoned veterans should consider reacquiring it for their current loadouts.
21% Delirium: Perk Synergy That Defies Time
This Rapid-Fire Frame Arc Machine Gun delivers impressive damage output through the synergistic combination of Killing Tally and Overflow. Killing Tally provides a substantial 30% damage increase that stacks up to three times, while Overflow automatically reloads the weapon from reserves when you collect ammo with a full magazine, effectively creating a self-sustaining damage cycle.
When enhanced with Backup Mag, Overflow enables 21% Delirium to hold an impressive 230 rounds, dramatically reducing reload frequency during intense combat scenarios. This exceptional ammunition capacity, combined with the damage buff, creates one of the most efficient add-clearing tools in Destiny 2’s heavy weapon arsenal. What makes this combination truly remarkable is that 21% Delirium remains the exclusive machine gun capable of rolling with this specific perk pairing.
Pro Tip: To maximize Killing Tally uptime, focus on eliminating weaker enemies first to build stacks before engaging tougher targets. The damage bonus persists through reloads as long as you don’t stow the weapon, making strategic target prioritization crucial for optimal performance.
Effortless Acquisition Strategy
One of 21% Delirium’s most appealing attributes is its straightforward acquisition process. Simply travel to the Tower and visit the Legacy Gear section within the Exotic Archive, where it’s available for a mere 75,000 Glimmer. This represents a significant reduction from previous requirements that also demanded x1 Ascendant Shard, x2 Enhancement Prisms, and x100 Legendary Shards—resources that are no longer necessary for Exotic Archive purchases.
Upon obtaining 21% Delirium from the Exotic Archive, you’ll receive this pre-configured roll:
- Barrel: Polygonal Rifling
- Magazine: Extended Mag
- Column Three: Overflow
- Column Four: Killing Tally

Common Mistake to Avoid: Don’t waste resources trying to farm a different roll—the curated version contains the ideal perk combination. Instead, focus those materials on masterworking the weapon or investing in other gear upgrades.
Practical Performance & Limitations
While 21% Delirium performs exceptionally in many scenarios, it’s important to acknowledge its limitations. As a 900 RPM Machine Gun, it consumes heavy ammunition rapidly, requiring careful ammo management during extended engagements. This ammo efficiency concern becomes particularly relevant in activities with limited heavy ammo drops or during sustained DPS phases against bosses.
Additionally, Rapid-Fire Frame machine guns currently occupy a niche position in the meta, with their restricted effective range presenting challenges in certain end-game content where engagement distances are longer. In activities like Grandmaster Nightfalls or Master raids, you might find yourself outranged by enemies that can damage you from outside your optimal engagement distance.
Optimization Strategy: Pair 21% Delirium with ammo finder mods and scavenger perks to mitigate ammo concerns. For range limitations, complement it with a long-range special weapon like a sniper rifle or scout rifle to cover all engagement distances effectively.
Weapon Comparison & Alternatives
When evaluating Arc machine gun options, 21% Delirium consistently ranks as the second-best choice, surpassed only by Song of Ir Yut. While Song of Ir Yut offers superior overall performance, it remains exclusive to the Crota’s End raid, requiring both a competent fireteam and RNG luck for acquisition.
Many players lack consistent raid teams or the time commitment required for raid farming, making this unsunset weapon their optimal alternative. The accessibility advantage cannot be overstated—while Song of Ir Yut might theoretically perform better, 21% Delirium delivers approximately 85-90% of its effectiveness with 100% acquisition certainty.
Advanced Tip: For players who do have both weapons, consider using 21% Delirium in content where add-clear efficiency matters most, and reserve Song of Ir Yut for boss DPS scenarios where every percentage of damage matters. This strategic allocation maximizes your loadout effectiveness across different activity types.
