Fulmin

Two-mode electric rifle

Released May 22, 2019

Fulmin switches between a short-range semi-auto electrical discharge and a hit-scan full-auto mode. Consider it when you want both a close-range burst and automatic fire in one primary weapon; Wisp switches modes faster according to its description.

Fulmin GUIDE

Understand Fulmin

Useful when…

  • Using Semi-Auto Mode for its listed Impact and Electricity projectile attack
  • Using Full Auto Mode for rapid hit-scan fire
  • Taking advantage of faster mode-switching when wielded by Wisp

How do the firing modes differ?

Full Auto Mode is hit-scan, listed at 9.33 shots per second, with 28% critical chance, a 2.4× critical multiplier, and 10% status chance. It deals Puncture and Electricity damage. Semi-Auto Mode is a projectile, listed at 2.17 shots per second, with 30% critical chance, a 2.2× multiplier, and 16% status chance. It deals Impact and Electricity, with listed falloff from 10 to 20 and 0.6666 reduction. The two modes should be evaluated separately: the normal properties' overall magazine and trigger fields do not replace the per-attack mode details.

When should you switch modes?

Use Full Auto Mode when hit-scan tracking and its faster listed fire rate are useful. Semi-Auto Mode deals a much larger listed per-shot damage profile and has higher status chance, but is a projectile with range falloff, so it is a more deliberate short-range option. The description calls this a stealthy short-range discharge and says Wisp switches faster. The supplied attack properties do not specify any other stealth interaction, so do not infer one beyond that description.

How does Fulmin Prime compare?

Fulmin Prime shares the two-mode concept and listed base critical chance and multiplier, but its detailed profile lists 34% critical chance for Full Auto Mode versus Fulmin's 28%, 22% status chance for Semi-Auto versus 16%, and a larger eight-round magazine versus six. It also has a Naramon polarity listed. Ambassador instead switches between charged explosive and rapid-fire electrical modes; Basmu offers explosive bolts and chaining plasma beams with a battery-related health-leech effect. Those alternatives have different mechanics and mastery requirements, rather than a single automatic recommendation.

Limitations and tradeoffs

  • The modes have different damage, critical, status, and projectile properties.
  • Semi-Auto Mode has listed falloff and projectile travel; Full Auto Mode is hit-scan.
  • Six-round magazine and three-second reload are listed overall.

Common mistakes to avoid

  • Do not use the Full Auto critical or status values for Semi-Auto Mode.
  • Do not treat Semi-Auto's projectile attack as hit-scan or ignore its listed falloff.
