Fires a high-damage piercing laser in the player's currently faced direction. The piercing property hits every enemy along the beam's path — a single shot through a dense column of enemies deals full damage to each. Per-shot damage is high, but the attack angle is strictly a single line, making consistent hit rate entirely dependent on aligning movement direction with enemy positions.

Unlocked by surviving 15 minutes with Lucia (Operation Guns DLC). The weapon's own description acknowledges it is "hard to hit with" — the narrow facing-direction constraint demands active angle management that other weapons don't require. Bracer is a natural companion: higher movement speed means faster direction changes, which directly improves how often enemies fall on the laser line.

Max C-U-Laser (Lv 8), carry Weapon Power-Up (randomly levels an equipped weapon + grants Revival +1), and open an elite-drop chest after 10:00 to evolve into Pronto Beam.

Pronto Beam Effect

After evolution lasers split into multiple beams when they hit an enemy. The split beams radiate outward from the impact point, substantially widening the weapon's effective coverage beyond the original single-line arc. The narrow-angle weakness is meaningfully reduced post-evolution.

• High per-shot damage — the piercing laser punishes dense enemy columns heavily
• Piercing property provides full efficiency against linearly clustered enemies
• Weapon Power-Up grants Revival +1, making the evolution path also a survival investment
• Post-evolution beam splitting covers a wide area around each impact point

• Requires the Operation Guns DLC
• Unlocked only by surviving 15 minutes with Lucia
• Strictly forward-facing — the game acknowledges the weapon is "hard to hit with"
• Pre-evolution has zero coverage of rear and side enemies

• Lucia: the unlock character; Operation Guns DLC character
• Characters with movement speed bonuses: faster direction changes improve the ability to keep enemies on the laser line
• Imelda: +10% Growth speeds evolution

• Weapon Power-Up: mandatory for evolution; Revival +1 is a meaningful safety bonus (top priority)
• Bracer: movement speed directly improves facing-direction control and laser alignment
• Spinach: +10% Might amplifies the already-high base laser damage
• Candelabrador: longer range extends the piercing laser's reach

• IX Divine Bloodline: crit compounding on high-damage laser hits delivers extreme DPS spikes
• IV Soul Eater: movement speed bonus further sharpens facing-direction control

• Early (0–10 min): Level C-U-Laser and secure Bracer early — the speed bonus is the most impactful quality-of-life improvement for this weapon. Practice keeping the movement direction pointed at the densest enemy cluster. Anticipate enemy approach angles to pre-align the laser.
• Mid (10–20 min): Collect Weapon Power-Up and evolve into Pronto Beam. The split beams immediately reduce the precision demand — enemies near the beam's impact point are caught even without perfect alignment.
• Late (20+ min): Pronto Beam's splitting combined with the high base damage handles dense forward clusters. Add Candelabrador to push range and catch enemies before they close to melee.

Q: How do I unlock C-U-Laser?
A: Survive 15 minutes with Lucia. The Operation Guns DLC is required.

Q: How do I deal with the narrow angle?
A: Bracer is the most direct counter — higher movement speed means faster direction changes. Additionally, committing to a straight path into the densest enemy cluster naturally aligns the laser. Post-evolution Pronto Beam's split beams substantially reduce the precision requirement.

Q: How does Pronto Beam's split work?
A: When the laser hits an enemy, it immediately splits into multiple beams that radiate outward from the impact point. This converts the single-line pierce into a wide-coverage area burst around each hit, dramatically improving coverage compared to the base weapon.
