Constructed by @Adamsdown_Boy (PvE PvE-Boss PvE-SustainedDamage PvE-EndGame M+KB Controller): Backup PvE roll for sustained DPS in a damage phase against a single yellow-bar target in activities rated Normal, Hard or Very Hard difficulty on Arc builds. Iterative Loop is a rapid-fire fusion rifle, which are rated F-Tier for endgame PvE by @TheAegisRelic tiering spreadsheet https://linktr.ee/TheAegisRelic being a "strict downgrade from high-impact and precision frames for boss damage". The frame intrinsic offers built in Anti-Overload, better total ammo reserves and a ×0.8 reload animation scalar when the battery is empty as per the https://www.destiny2.science/ Destiny Data Compendium. The stats are decent by comparison with its peers - you can see them at https://destiny.report/w/1289796511/iterative-loop and hopefully https://d2foundry.gg/w/1289796511 will show how weapon stats impact in-game performance when the site is back up and running. With 9 bolts to control, look for a barrel perk that helps with recoil control together with any other stat that you want to bump. As the battery perk, Accelerated Coils improves charge time by 40ms at the cost of ×0.98 base damage, or Enhanced Battery gets you to the maximum of 7 shots. While losing out to precision and high-impact frames for total boss damage, if you wanted one for ease of use, then on Arc builds, Supercharged Magazine refills 5% of the magazine every 1.5s while you're Amplified or, after you sprint when Amplified to gain Speed Booster this accelerates to 5% every 0.25s while the buff is active, overflowing the magazine to up to ×2 capacity. In the second column, for damage, Controlled Burst reduces charge time to ×0.9 and boosts damage by ×1.2 for 2s (2.5s when enhanced) after a kill or landing all the bolts in a burst. The Nanotech Tracer Missile origin trait generates a tracking elemental micro missile for extra damage for landing 3 bursts on a target within 6s of each other - with a 2s cooldown. If you're interested, in computer science and mathematics, an iterative loop is a process that repeats a stepwise routine, gradually refining, adjusting, or updating an object or code toward a desired result until perfection is approached. Recommended MW: Charge Time, with a Charge Time mod or your preferred choice to boost weapon stats, ammo generation, or elemental pickups for builds.|tags:PvE PvE-Boss PvE-SustainedDamage PvE-EndGame M+KB Controller

Iterative Loop is a rapid-fire fusion rifle, which are rated F-Tier for endgame PvE by @TheAegisRelic tiering spreadsheet https://linktr.ee/TheAegisRelic being strict downgrade from high-impact and precision frames for boss damage.

For dealing with groups of Minor adds, in the first trait perk column Compulsive Reloader provides +50 Reload Speed (+55 when enhanced) with a ×0.95 reload animation scalar when the battery is above 50% charge. In the second column, Voltshot applies Arc Jolt to the next target you hit within 7s (8s when enhanced), after a reload within 5.3s of a kill, for additional damage to the target on further hits plus AoE chain lightning damage on nearby enemies.

pandapaxxy (PvE / M+KB / Controller): Recommended MW: Reload. Rapid-Fire(500) Arc Fusion Rifle Special Ammo. "Iterative Loop needs better recoil direction. You might almost want to run counterbalance mod on it at all times. Accelerated Coils bumps up your damage per second. Lead from Gold is a very fun build and this could be a great major / champ killer. Compulsive Reloader and Voltshot would make a great pairing and clear rooms quickly. Not quite as strong as Reservoir Burst but an interesting arc alternative."

pandapaxxy (PvP / Controller): Recommended MW: Range. Rapid-Fire(500) Arc Fusion Rifle Special Ammo. "Over in the Crucible void mains will be happy. Under Pressure and Elemental Capacitor will make this weapon feel like it doesn’t move. Another incredible combo would be Under Pressure and Kickstart. Pair those two with heavy investments into charge time and you will have a 336ms anti-shotgun. This might almost fire so quickly you won’t be able to precharge as often or aim as well. Another issue is you have to be sliding which on MnK you can slide180 our controller players will not be able to as reliably. Making this lean more towards one input over another."

Inspired by @PodvsEnemies Podcast Versus Enemies episode 54 with @CourtProjects, @ImpetusAlways and @Saint_Kabr (https://open.spotify.com/episode/3obSAgsEW0RBeSjYXOVcgN?si=95ac723a75f749c3). First-choice PvE roll for Arc synergy and burst damage. Seeing as fusion rifles apply the highest Jolt tick damage of any special weapon, it would be rude not to pick or shape a roll. Rapid fire fusions need a fair bit of control with nine bolts being fired, so Arrowhead Break takes the recoil direction to 77, or up the stability through Fluted Barrel or Polygonal Rifling. In the battery, there's nothing to help speed up reloading, so Particle Repeater adds more stability, or Accelerated Coils speeds up charge time. Compulsive Reloader and a Reload Speed Masterwork boosts reload to 100 at the top half of the mag, so your reloads after a kill to proc Voltshot should be as snappy as it's possible to get. On top, the Nanotech Tracer Rockets add both damage and flinch when you proc them with rapid kills - really fun for PvE. Recommended MW: Reload Speed or Stability, with a damage-boosting (Major, Boss or Taken Spec) or Backup Mag mod.|tags: PvE, PvE-Boss, PvE-MajorSpec, PvE-BossSpec, PvE-God, Controller, M+KB
