A uniquely support-oriented weapon that restores HP rather than dealing damage. Each activation heals the player for an amount determined by two stats simultaneously: Amount increases how many restoration pulses fire per cycle, and Recovery increases how much HP each pulse restores. Unlike any standard weapon, Lifesign Scan occupies a weapon slot and contributes zero direct damage — its value comes entirely from sustain, enabling the remaining weapon slots to be allocated purely to offense.

The dual-scaling model (Amount × Recovery) allows building toward either direction: stacking Amount through Duplicator delivers more frequent smaller heals, while stacking Recovery delivers larger heals per pulse. Combining both produces sustained HP recovery that can outpace damage intake even at high enemy density. Lifesign Scan is a DLC weapon unlocked by picking it up during a run with the Porous Replica character.

Max Lifesign Scan (Lv 8), carry Mini Ghost, and open an elite-drop chest after 10:00 to evolve. The post-evolution weapon name is currently unconfirmed.

• Unique heal-over-time weapon — no other weapon occupies a slot to provide this volume of continuous HP recovery
• Dual Amount and Recovery scaling provides two independent axes for increasing heal output
• Removing health management pressure lets the remaining five weapon slots commit fully to damage output
• Pairs well with any aggressive playstyle that would otherwise require frequent repositioning to avoid damage

• Evolution destination currently unknown
• Requires DLC ownership and picking it up with a specific DLC character to unlock
• Zero direct damage contribution — team DPS comes entirely from the other weapon slots
• Only effective if the other weapons are strong enough to compensate for the lost damage slot

• Porous Replica: the unlock character; likely has native synergies with the healing mechanic
• Any character in a difficult-survival run: continuous regen dramatically extends survivability in long runs
• Imelda: +10% Growth levels Lifesign Scan faster for earlier evolution timing

• Mini Ghost: mandatory for evolution; provides unique passive buffs (top priority)
• Duplicator: Amount increase adds more heal pulses per cycle for higher heal-per-second
• Parmigiano: Recovery increase raises HP restored per pulse
• Pummarola: HP max increase raises the ceiling that Lifesign Scan can heal up to — more maximum HP means more total recoverable health

• VI Sarabande of Healing: additional healing interactions may stack with Lifesign Scan's sustained regen
• III Tragic Princess: Amount increase adds more healing pulses per activation cycle

• Early (0–10 min): Level Lifesign Scan and secure Pummarola and Duplicator. Higher HP max and more healing pulses per second establish a health loop that compensates for early-game damage intake. With healing stable, shift remaining slots entirely to damage output.
• Mid (10–20 min): Carry Mini Ghost and push to Lv8 for evolution. With regen established, take aggressive positions inside enemy clusters — Lifesign Scan heals back damage taken in real time, enabling otherwise-unsustainable attack positioning.
• Late (20+ min): At high Amount and Recovery, Lifesign Scan heals faster than most enemy attacks can deal damage, effectively removing health as a constraint. The freed design space in the other five weapon slots compounds — all five can be damage-optimized without any defensive hedging.

Q: How do I unlock Lifesign Scan?
A: Pick it up as a field item during a run using the Porous Replica DLC character. The DLC must be owned and Porous Replica must be the active character. The item spawns on the stage and is collected on contact.

Q: Is a weapon that deals no damage worth a slot?
A: Yes, in the right build. Lifesign Scan's regen can sustain aggressive positioning that would otherwise be suicidal — the net effect on run output depends on whether the other five slots can compensate for the lost damage slot with higher-quality weapons than they would otherwise have. In regen-focused builds, the answer is usually yes.

Q: What stat boosts Recovery?
A: Parmigiano is the primary passive that raises the Recovery stat. Higher Recovery increases the HP restored per individual healing pulse from Lifesign Scan.
