Inspired by @PodvsEnemies episode 153 from 9 September 2025 (https://open.spotify.com/episode/6iEksMDGzT5euNuMAEqnVm?si=a9bf49987cdb441a) with @CourtProjects and @Saint_Kabr (PvE PvE-PvE-MinorSpec PvE-God PvE-EndGame M+KB Controller): First-choice PvE roll for dealing with Minor adds in both general at-level or better, and end-game underleveled content. Mercury-A is the first of a new bow subfamily - high-impact longbows - whose frame intrinsic is to overpenetrate targets, like Armor-Piercing Rounds. There aren't really any peers to assess against - the weapon has higher impact and stability (so a longer perfect draw window), but longer draw time and worse attributes in every other respect, although that's helped at Tier 4/5 when bowstring and arrow perks are enhanced - see https://d2foundry.gg/w/2838279629 for how the weapon stats impact in-game performance. You'll definitely need to use the bowstring perk to improve Draw Time, and the arrow perk to recover any lost Accuracy or improve Reload Speed to improve the time before you're ready to shoot again. In the absence of Archer's Tempo in the first trait perk column to help with Draw Time, there is Successful Warm-Up which applies a ×0.625 scalar after a kill for 6s, with further kills adding 4s (5s when enhanced) at a time to a maximum of 20s or until stowed. In the second column, you can pair that with Kinetic Tremors to emit three 6m AoE kinetic shockwaves after 3 crit hits (2 enhanced). On Prismatic, there's also Elemental Honing which grants an escalating stack of damage up to ×1.4 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. The Tenacity Origin trait stacks up to ×20 on kills, providing +2.5 Handling and Reload Speed and an extra 0.5% damage per stack (max +50 Handling and Reload, and ×1.1 damage boost) until you die. Vanguard Vindication provides up to 3 stacks of ×0.98/0.96/0.94 damage reduction for 10s, for kills within 20s of using a class ability. There's also Häkke Breach Armaments for an additional ×1.15 damage against vehicles, ×1.3 damage against constructs and ×1.45 damage against stasis crystals. Recommended MW: Draw Time, with your preferred choice of mod/enhanced mod to boost mag size, weapon stats, ammo regeneration, or elemental pickups for builds - and don't forget to check any available seasonal fragile mods.|tags:PvE PvE-PvE-MinorSpec PvE-God PvE-EndGame M+KB Controller

You'll definitely need to use the bowstring perk to improve Draw Time, and the arrow perk to recover any lost Accuracy or improve Reload Speed to improve the time before you're ready to shoot again. For an all-round roll there's a useful interaction in the trait perk combination of Attrition Orbs to spawn a power orb after 5 hits within 5s of each other, to help super generation and proc armour mods and Kinetic Tremors to emit three 6m Aoe kinetic shockwaves after 3 crit hits (2 when enhanced) emits three 6m AoE kinetic shockwaves after 3 crit hits (2 when enhanced) which are treated as weapon damage and inherit damage boosts, and also procs weapon effects like proccing Attrition Orbs' orb generation. The Tenacity Origin trait stacks up to ×20 on kills, providing +2.5 Handling and Reload Speed and an extra 0.5% damage per stack (max +50 Handling and Reload, and ×1.1 damage boost) until you die.

What these Mercury-A perks do

Attrition Orbs

Scoring multiple Hits against enemies within 5 seconds of each spawns an Orb of Power that grants 0.8% Super Energy. Does not require Direct Hits. Hit counter persists through stow. Hit requirements for activation: • Rocket Launchers: 2 hits • Heavy Grenade Launchers: 3 Hits • Wave-Frame Grenade Launchers: 4 hits • Bows: 4 Hits • Swords: 5 Hits • Area-Denial Grenade Launchers: 26 Hits • Others: 55% of Magazine Size rounded down + 1 Support Frame Auto Rifle healing round Hits on damaged allies count as 2 Hits.

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

Successful Warm-Up

Weapon Kills decrease Charge/Draw Time by 37.5% for 6 seconds. Kills while the perk is active add 4 seconds to the duration up to a maximum of 20 seconds. Buff is removed on stow.

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%
