Fires a single penetrating projectile in the player's current facing direction. Unlike standard projectiles that stop on the first enemy contact, Javelin's projectile passes through each enemy it hits and continues traveling — dealing its full damage to every enemy along the line until the projectile expires at range. A column of ten enemies aligned with the shot direction all take full damage from a single throw.

Facing direction is fixed at the moment of firing (typically the last movement direction), so positioning to face the densest enemy flow before triggering is the core skill expression of the weapon. Forbidden Scrolls as the evolution material is shared with Ice Fang — both weapons compete for the same passive slot, so a build running both must choose which evolution to pursue.

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

• Penetration means a single projectile damages every enemy aligned on the throw line — total damage scales directly with enemy count on axis
• Fixed direction eliminates trajectory variance — every fired projectile hits exactly where the player is facing
• Low unlock threshold (reach level 3 in any run) makes it accessible without completing specific challenges
• High Projectile Speed extends reach and allows penetration further down longer enemy columns

• Evolution destination currently unknown
• Coverage is strictly unidirectional — enemies approaching from sides or behind take no damage
• Forbidden Scrolls is shared with Ice Fang's evolution, forcing a choice between the two
• Scattered enemy formations reduce penetration value per projectile, falling behind non-penetrating weapons in those scenarios

• Characters focused on concentrated directional firepower: pair Javelin with other facing-direction weapons for amplified linear damage
• Imelda: +10% Growth levels Javelin faster for earlier maximum damage output
• High Projectile Speed characters: faster projectiles travel farther and pass through longer enemy formations

• Forbidden Scrolls: mandatory for evolution; provides unique passive buffs (top priority)
• Spinach: +10% Might raises damage per penetration hit
• Bracer: Projectile Speed increase extends throw distance — longer reach means the projectile passes through more enemies before expiring
• Duplicator: Amount increase adds more simultaneous throws, covering multiple facing-direction lines at once

• IX Divine Bloodline: crit compounding on each penetration hit raises DPS
• III Tragic Princess: Amount increase adds simultaneous throws for broader directional coverage
• XX Silent Old Sanctuary: Projectile Speed boost extends throw range further

• Early (0–10 min): Level Javelin and secure Forbidden Scrolls early. Focus movement on facing the direction of the densest incoming enemy waves — the penetration value only pays off when enemies line up on the throw axis.
• Mid (10–20 min): Carry Forbidden Scrolls and push to Lv8 for evolution. Add Bracer to increase throw range — longer-traveling projectiles pass through more enemies per throw and extend effective coverage further into incoming waves.
• Late (20+ min): Standing at the mouth of enemy approach corridors and facing incoming flows lets each Javelin throw punch through dense columns of enemies simultaneously. Multiple throws from Duplicator cover additional approach angles in parallel.

Q: How do I unlock Javelin?
A: Level Javelin to level 3 during any run. Select it from a weapon offer and level it up — no specific challenge condition beyond reaching level 3 is required.

Q: Is it a problem that Forbidden Scrolls is shared with Ice Fang?
A: Only if you are running both weapons simultaneously. In that scenario, decide early which weapon to evolve — carry Forbidden Scrolls and max whichever you prioritize first, then leave the other at max without evolving. Running both in the same build without planning the Forbidden Scrolls usage leads to an evolution dead end.

Q: What is the difference between penetrating and non-penetrating?
A: A non-penetrating projectile stops and disappears on the first enemy hit. A penetrating projectile continues through that enemy and hits every subsequent enemy along the trajectory until range is exhausted. The practical result: ten enemies lined up take ten full damage hits from one throw instead of one.
