Inspired by @Saint_Kabr and @ImpetusAlways (PvE PvE-Minor PvE-GroupAdd PvE-EndGame PvE-God M+KB Controller): First-choice PvE roll for clearing groups of Minor adds in activities rated Normal, Hard and Very Hard difficulty. Blast Furnace is back! It's still an Aggressive Burst pulse rifle which as a subfamily are currently rated D-Tier for endgame PvE by @TheAegisRelic Endgame Analysis spreadsheet in https://www.destiny2.science/ as "essentially just a poor high-impact auto, but arguably worse due to 4-burst nature". The frame intrinsic offers built-in anti-Unstoppable and fires a four-round burst as per the https://www.destiny2.science/ Destiny Data Compendium. The stats make this the best in class by comparison with its peers - you can see the stats at https://destiny.report/w/2631356658/blast-furnace and hopefully https://d2foundry.gg/w/2631356658 will show how weapon stats impact in-game performance when the site is back up and running. The recoil is vertical and a bit loose, so to tighten that up, look for a barrel perk that helps with Recoil Direction or, if you can handle it just go for extra handling, and then with the magazine perk go for something that helps improve magazine size or reload. For clearing groups of adds in general content, in the first trait perk column Kinetic Tremors emits three 6m AoE Kinetic shockwaves after 11 hits (10 when enhanced) within 3s of each other, which are treated as weapon damage so can inherit damage boosts from Chaos Reshaped in the second column, which stacks up to ×2 on dealing or recoving damage within a 5s window for at least 12s (11.5s when enhanced) - at ×1 it provides a ×1.2 damage boost for a refreshable 7s and then at ×2 provides ×1.35 damage for a refreshable 7s together with a healing burst of up to 35HP that also starts health regeneration. The Forge's Kin origin trait provides a ×1 stack of "Forge's Kin" for 5s after a kill, or on swapping from another Black Armory weapon kill within 7s. Each additional Black Armory weapon equipped adds an additional stack, each boosting the activation window by +2s together with increasing Reload Speed and Ammo Generation and damage boosts of ×1.05 and ×1.07 (×1.1 and ×1.13 enhanced). Alternatively, kills with the Indomitability origin trait provides 5% melee energy with a Darkness super equipped or 5% grenade energy with a Light super (6% for either enhanced). If you're interested, a blast furnace is an industrial smelter that relies on extreme, searing heat and a continuous blast of air to melt down raw iron ore into usable metal. Recommended MW: Handling, with your preferred choice of mod to boost weapon stats, ammo generation, or elemental pickups for builds.|tags:PvE PvE-Minor PvE-GroupAdd PvE-EndGame PvE-God M+KB Controller

For clearing groups of adds in general content, in the first trait perk column Bewildering Burst procs for 6s (7s when enhanced) after finishing a reload following a kill, and then on the next hit launches a kinetic flashbang above the target that does damage and disorients enemies within 9m for 3.5s. In the second column, Firefly procs a 4m AoE Solar explosion on a crit kill plus +50 Reload Speed for 6s to help with proccing Bewildering Burst. The Forge's Kin origin trait provides a ×1 stack of "Forge's Kin" for 5s after a kill, or on swapping from another Black Armory weapon kill within 7s.

What these Blast Furnace perks do

Chaos Reshaped

Being in Combat for 12 seconds grants a Stack of 'Chaos Reshaped' for 7 seconds. Maintaining the first Stack for 12 seconds grants a second Stack. Buff can be activated while stowed. For Chaos Reshaped, being in Combat is defined as having either dealt or received damage within the last 5 seconds. Benefits at Chaos Reshaped x1 and x2: • x1: grants 20% increased damage • x2: grants 35% increased damage and grants a periodic burst of healing Healing effect is bugged! While Chaos Reshaped x2 is active: Stowing the weapon or keeping it readied for 7 seconds grants a continous healing effect of 5 HP per second. Stowing this weapon grants the effect for 1 to 7 seconds (cycling, it's complicated), while keeping it readied after activation makes the healing effectively constant. While this healing effect is active, NO OTHER SOURCE OF HEALING CAN RESTORE THE FINAL [~35 to 5] HP OF YOUR HEALTH BAR! This unrecoverable HP segment can only be healed by Chaos Reshaped's 5/HPs effect. For more details, visit the perk description in the Destiny Data Compendium.

Kinetic Tremors

Scoring multiple Direct Hits against a target within 3 seconds of each emits 3 damaging shockwaves from its location at the time of activation. Hit counter persists through stow. Shockwaves appear 0.25 seconds after scoring enough Hits and have a 1 second delay between each pulse. With Bows, the initial delay is decreased to 0.167 seconds. Each shockwave deals up to 90 [20] damage in a 6 meter radius. Shockwaves deal 33.33% more damage when activated on Miniboss or higher tier PvE Combatants. Shockwaves inherit Weapon Damage Buffs, the weapon's passive Kinetic Damage Bonus in PVE (10% on Primary, 15% on Special), and its Combatant Damage Scaling. They also count as non-direct Hits with the weapon for other interactions. The perk cannot be retriggered by anyone on a target until 2? seconds after the last shockwave. Hits required for Activation: • Submachine Guns: 14 • Auto Rifles: 12 • Pulse Rifles: 11 • Sidearms: 8 • Precision Hand Cannons and Precision Scout Rifles: 6 • Hand Cannons, Scout Rifles: 5 • Bows, Sniper Rifles: 3

Alloy Magazine

Linearly grants a Reload Duration Multiplier as your magazine drops from 50% capacity to empty. Reload Duration Multiplier scales from 0.9x at 50% capacity to 0.8x with an empty magazine.

Bewildering Burst

Finishing a reload within ? seconds of a kill grants 'Bewildering Burst' for 6 seconds. While Bewildering Burst is active, your next Direct Hit spawns a Kinetic explosive above the target that detonates after a 0.85 second delay. The detonation deals 10 [4] damage and Disorients enemies within a 10 meter radius for 3.5 [1] seconds.

Firefly

On Precision Kills: • Target explodes, dealing 104 [80] Solar damage in a 4 meter radius • Grants 50 Reload Speed for 6 seconds
