Inspired by @CourtProjects, @Saint_Kabr and @ImpetusAlways (PvE PvE-Boss PvE-BossSpec PvE-God PvE-EndGame M+KB Controller): First-choice PvE roll for sustained damage against bosses in both general at-level or better, and end-game underleveled content. The When and Where is an adaptive frame rocket launcher, so benefits from ×1.1 base damage. The stats are solid by comparison with its peers, and they're helped further at Tier 4/5 when barrel and magazine perks are enhanced - see https://d2foundry.gg/w/1090936013 for how the weapon stats impact in-game performance. From @mossy_max's spreadsheet (https://destiny2.science/reserves), total ammo is 9. Most boss damage setups rely on weapon swaps, so Handling is key with the barrel trait, although higher Velocity is good to have too. For the magazine perk, Impact Casing increases impact damage by ×1.1 - which is ×1.022 overall, or to help with manual reloads, Alloy Casing or High-Velocity Rounds also work. For sustained damage against bosses, in the first trait perk column, Overflow overflows the magazine by ×2 (×2.2 when enhanced), rounded up, on picking up an ammo brick - so that's 3 in the mag for the enhanced version. There's also Reconstruction to refill the magazine every 6s (5.5s enhanced) up to ×2 capacity when stowed or not firing, or Clown Cartridge to load two in the mag on a manual reload. There are quite a few second column damage options - for longer DPS windows, Bait and Switch boosts damage by ×1.3 for 10s (11s enhanced) for doing damage with your other two weapons. Elemental Honing needs a little more setup, but grants escalating damage stack up to ×1.35 for 20s (23s enhanced) for each elemental damage type inflicted, which can be refreshed with a new damage type until you've run through all 5. For shorter windows, Reaper's Tithe generates a stacking damage buff on simultaneous kills, from ×1.2 at two kills to ×1.4 at four for a 15s (17s enhanced) with a 6s refresh on further kills - the timer only starts after the first shot with the damage buff active. Finally, Explosive Light generates up to 6 stacks (7 enhanced) on orb pickup, with buffed shots having maximum 100 blast radius and ×1.25 damage boost. The Frame of Reference Origin Trait stacks up to ×5 times on kills, providing up to ×1.07 damage and boosts to Reload Speed and Range for 8s, with the timer pausing when the weapon's stowed. Recommended MW: Handling or Velocity, with your preferred choice of mod/enhanced mod to boost weapon stats, ammo regeneration, or elemental pickups for builds - and don't forget to check any available seasonal fragile mods.|tags:PvE PvE-Boss PvE-BossSpec PvE-God PvE-EndGame M+KB Controller

Inspired by @CourtProjects, @Saint_Kabr and @ImpetusAlways (PvE PvE-Boss PvE-BossSpec PvE-God PvE-EndGame M+KB Controller): First-choice PvE roll for burst damage against Banes, Elites, Champions and Minibosses in both general at-level or better, and end-game underleveled content. The When and Where is an adaptive frame rocket launcher, so benefits from ×1.1 base damage. The stats are solid by comparison with its peers, and they're helped further at Tier 4/5 when barrel and magazine perks are enhanced - see https://d2foundry.gg/w/1090936013 for how the weapon stats impact in-game performance. From @mossy_max's spreadsheet (https://destiny2.science/reserves), with Bipod, base mag size is 2 and total ammo is 14. Most boss damage setups rely on weapon swaps, so Handling is key with the barrel trait, although higher Velocity is good to have too. For the magazine perk, Impact Casing increases impact damage by ×1.1 - which is ×1.022 overall, or to help with manual reloads, Alloy Casing or High-Velocity Rounds also work. For burst damage against bosses, in the first trait perk column, Overflow overflows the magazine by ×2 (×2.2 when enhanced), rounded up, on picking up an ammo brick - so that's 5 in the mag for the enhanced version. There's also Reconstruction to refill a shot every 6s (5.5s enhanced) up to four in the mag when stowed or not firing, or Clown Cartridge to load two or three in the mag randomly on a manual reload. In the second column, Bipod trades having two rockets in the chamber at base, for burst damage, for -20 to Blast Radius and Reload Speed (-15 to Reload Speed when enhanced) and a damage reduction of ×0.75. The Frame of Reference Origin Trait stacks up to ×5 times on kills, providing up to ×1.07 damage and boosts to Reload Speed and Range for 8s, with the timer pausing when the weapon's stowed.

What these The When and Where perks do

Bait and Switch

Dealing damage with a weapon starts a 7 second timer. Dealing additional weapon damage resets the timer to 7 seconds. Dealing damage with all 3 of your weapons without letting the timer run out grants you 'Bait and Switch' for 10 seconds, granting 30% increased damage. Timer is disabled while Bait and Switch is active, requiring a full activation sequence once the buff expires.

Overflow

Upon picking up Special or Heavy Ammo: Refills and Overfills the Magazine from reserves. Overfill amount maxes out at 100% of the Magazine Capacity. Activates even while stowed.

Impact Casing

Increases Impact damage by 10%, resulting in a 2.2% total damage increase (not accounting for other damage perks). High-Impact Rocket Launchers only receive a 1.03% total damage increase.

Elemental Honing

Dealing Elemental Damage grants a stack of Elemental Honing for 20 seconds for each unique Element used. Maximum of 5 stacks. Gaining a stack refreshes the buff duration. Duration cannot be refreshed once at 5 stacks. Buff can be activated while stowed. Kinetic Damage does not trigger the buff. Weapon damage increase at 1|2|3|4|5 stacks by weapon damage type: • Kinetic: 10%|20%|30%|35%|40% • Elemental (PVE): 2.5%|10%|20%|30%|35% • Elemental (PVP): 1.25%|5%|20%|30%|35%

Reaper's Tithe

Grants stacks of 'Reaper's Tithe' based on the number of simultaneously killed enemies. Maximum of 4 stacks. (e.g. triple kill ⇒ 3 stacks) 'Reaper's Tithe' grants 20%|30%|40% increased damage for 15 seconds at 2|3|4 stacks (1st stack does not exist). Timer only starts after firing. Additional Weapon Kills extend the buff duration by 6 seconds, but not beyond the initial 15-second duration. Scoring a higher number of simultaneous Kills than the currently active stack count will not "upgrade" the buff.

Explosive Light

Orb of Power pickups (even while the weapon is stowed) grant 1 Stack of Explosive Light. Maximum of 6 Stacks. Firing the weapon comsumes 1 Stack per Shot, granting increased damage and 100 Blast Radius. Grenade Launchers: 60% increased Explosive damage. Rocket Launchers: 25% increased Impact and Explosive damage. (Does not affect Wolfpack Rounds)

Reconstruction

Every 6 seconds while not firing the weapon: Loads 25% of the Magazine Capacity (rounded up) into the Magazine from reserves. Can overfill the Magazine up to double the normal capacity. Works even while stowed.

Clown Cartridge

Reloading randomly overfills the Magazine from reserves by 10% to 50% of the base Magazine Capacity (rounded up). Works out to a 30% overfill on average.

Bipod

Increases Magazine Capacity by 1 and Total Reserve Size by 5. Decreases Firing Delay by 25%. Decreases Blast Radius by 30, Reload Speed by 20, and damage by 25% (also applies to Wolfpack Rounds and Cluster Bombs).
