What Bluecurrent Pulse actually does

Bluecurrent Pulse is a ranged weapon that does three important things at once: it extends skill uptime, it boosts dual pistols damage after you tag an enemy, and its shots can bounce for extra hits. In practice, that means steadier ability windows and a large, time‑limited power spike to your pistol strings.

Effect How it helps Notes
Increases Skill Duration (e.g., +30%) Keeps summons/fields and buff windows active longer Particularly valuable for skill‑centric rotations
Dual pistols damage buff on hit Big damage spike for pistol sequences Scales with upgrades, up to a very high value (commonly cited at 90%) for ~30s
Projectile bounce (1) Extra contact for procs and add clear Helps maintain pistol buff uptime in groups

How to get Bluecurrent Pulse

You can purchase Bluecurrent Pulse directly from the in‑game Shop for 3280 Phoxene Plumule, the game’s premium currency. If you plan to buy it this way, budget for refinement and enhancement materials as well—its pistol damage buff scales noticeably with upgrades.

Note: Phoxene Plumule is a paid currency. If you prefer not to spend, consider timing purchases with events or bundles that include upgrade materials.

Why Bluecurrent Pulse over Excresduo in many Lynn builds

There’s a common debate between Bluecurrent Pulse and Excresduo for Lynn. Excresduo offers a rare, broad Skill Damage bonus—great for pure ability nukes. Bluecurrent Pulse, on the other hand, supercharges pistol output while still improving uptime on abilities. For Lynn’s most popular Pyro DPS setups, that pistol spike is the difference maker, not the Skill Duration line by itself.

Weapon Primary value Best when Trade‑offs
Bluecurrent Pulse High dual pistols damage buff + Skill Duration + bounce Your rotation leans on sustained pistol strings with frequent skill windows Buff is time‑limited; benefits scale with refinement
Excresduo Flat Skill Damage bonus (rare stat) Your kit is overwhelmingly ability‑driven and less reliant on pistol chains No pistol‑specific spike; less synergy with basic/ranged sequences

Lynn Bluecurrent Pulse build (Pyro DPS)

Lynn’s mainstream Pyro DPS path pairs Bluecurrent Pulse for ranged with a melee sidearm that keeps Pyro pressure high.

  • Melee: Pyrothirst
  • Ranged: Bluecurrent Pulse

How to play it:

  • Open with ranged shots to activate the pistols damage buff window.
  • Weave Pyrothirst melee when you need element application or to bridge cooldowns, but keep returning to pistol strings to capitalize on the buff duration.
  • Leverage the Skill Duration increase by aligning your Pyro windows inside the pistol buff timer. The bounce helps keep the buff rolling in mob fights.
Tip: Bluecurrent Pulse is preferred here primarily for the pistol damage spike. The extra Skill Duration is helpful, but it’s not the main reason to slot it.

Berenica Bluecurrent Pulse build (Umbro DPS)

Berenica’s kit benefits from the longer Skill Duration and, more importantly, the pistol damage spike. She thrives on agile ranged sequences with short melee punctuations.

  • Melee: Remanent Reminiscence
  • Ranged: Bluecurrent Pulse

How to play it:

  • Tag enemies with Bluecurrent Pulse to trigger the pistol buff, then lean into her dual pistols to cash in on the window.
  • Use the bounce to maintain contact across clustered targets; it helps both add clear and uptime.
  • Rotate melee only to reposition, recover resources, or extend invulnerability windows—then return to pistols while the buff is active.

Who else wants Bluecurrent Pulse

Any ranged‑leaning DPS whose rotation loops through pistols or relies on persistent skill effects benefits here. The weapon’s value rises if:

  • Your team lacks other large pistol or normal‑hit multipliers.
  • Your character’s best damage pattern lives in a sustained, repeatable window rather than a single, long cooldown nuke.
  • You need extra coverage to keep multi‑target contact without repositioning every second.

Upgrade and refinement priorities

Bluecurrent Pulse pays off quickly with investment because its defining pistol buff scales with upgrades. If you’re resource‑constrained, prioritize:

  • Unlocking the pistol damage buff breakpoint you can sustain with your current materials.
  • Enhancement levels that increase base weapon stats to support consistency in your main rotation.
  • Refinement before over‑leveling other off‑hand pieces if your build’s damage profile is pistol‑heavy.
Tip: If you’re torn between acquiring Bluecurrent Pulse and a pure Skill Damage weapon for a skill‑only team, decide based on who you plan to main. Lynn and Berenica make excellent use of Bluecurrent now, while strictly ability‑centric characters may prefer the Skill Damage route first.

Cost, timing, and team planning

Buying Bluecurrent Pulse for 3280 Phoxene Plumule is a significant investment. Make it count by planning your team around its strengths:

  • Include supports that extend or amplify ability windows to stack with the Skill Duration increase.
  • Bring debuffs or aura fields that pistols can repeatedly trigger inside the buff window.
  • Avoid rotations that force you out of pistol stance during the buff unless you’re gaining a bigger payoff elsewhere.

If your main DPS spends most of their time on pistols and cycles abilities often, Bluecurrent Pulse is an easy recommendation. It’s the right mix of uptime and punch for Lynn and Berenica, and it scales well as you invest. If your plan leans into pure ability nukes with minimal pistol usage, a Skill Damage weapon like Excresduo remains a valid alternative.
