Fulmin Prime

Two-mode electric rifle with Prime variant stats

Released Jul 27, 2023

Fulmin Prime combines rapid hit-scan Full Auto Mode with a projectile Semi-Auto Mode that deals Impact and Electricity. Consider it when both attack styles are useful; its mode-specific stats differ, and Wisp switches modes faster according to the description.

Fulmin Prime GUIDE

Understand Fulmin Prime

Useful when…

  • Using Full Auto Mode for rapid hit-scan fire
  • Using Semi-Auto Mode for its higher listed per-shot damage and status chance
  • Using Wisp for the described faster mode switching

What does each mode do?

Full Auto Mode is hit-scan at a listed 9.33 shots per second, with 34% critical chance, a 2.4× critical multiplier, and 10% status chance. It deals Puncture and Electricity. Semi-Auto Mode is a projectile at 2.17 shots per second, with 30% critical chance, a 2.2× multiplier, and 22% status chance; it deals Impact and Electricity. Its listed falloff starts at 12 and ends at 24, with 0.6666 reduction. The modes are distinct: do not apply Semi-Auto's status chance or projectile falloff to Full Auto.

What handling and fitting details matter?

The overall properties list an eight-round magazine and 2.7-second reload. Semi-Auto is a projectile and has falloff, so it suits closer, deliberate shots better than relying on it for distant moving targets. Full Auto is hit-scan and fires much faster. One Naramon polarity is listed, which can reduce capacity cost for matching mods in that slot; it does not prescribe a full mod setup. Wisp's faster switching is a stated frame-specific handling benefit.

How does it compare with related rifles?

The base Fulmin shares the listed 30% overall critical chance and 2.2× critical multiplier, while the detailed attack properties differ: Fulmin Prime lists Full Auto at 34% critical chance and Semi-Auto status at 22%, compared with 28% and 16% for the base version. Ambassador offers charged explosive and rapid-fire electrical modes. Basmu uses explosive bolts or chaining plasma beams and has a battery-related health-leech effect. These descriptions help distinguish mechanics, but do not establish a universal upgrade ranking.

Limitations and tradeoffs

  • Semi-Auto Mode has projectile travel and range falloff.
  • The two modes have separate critical, status, and damage properties.
  • Eight-round magazine and 2.7-second reload are listed overall.

Common mistakes to avoid

  • Do not transfer Full Auto's 34% critical chance to Semi-Auto Mode.
  • Do not assume the Semi-Auto projectile shares Full Auto's hit-scan behavior.
