Saying that making a dual-fire rifle good is like catching lightning in a bottle is less of a testament to the difficulty of making good weapons in Warframe and more of a blueprint for the Fulmin. Colloquially referred to as the “lightning gun”, it is one part Tenora and one part Arca Plasmor – quite literally.
The Fulmin rifle has two fire modes, the first is a silent pulse of Electricity Damage much like the Arca Plasmor, and the second is a full-auto mode that shoots rounds at a decent pace. The Fulmin is the signature weapon of Wisp and as such has a small bonus when being wielded by the ghostly gal – the Fulmin’s alt-fire takes half as long to fully switch.
This rifle is also another example of a battery weapon. After a brief period without firing, the Fulmin will begin recharging its ammo store. The Fulmin is both fun to use and highly useful in a number of situations, its innate Electricity Damage can be built for Corrosive or Radiation to bypass enemy Armor or Shields respectively, and the dual-fire mode can be used to swap between short and mid-range engagements on the fly. Overall, the Fulmin is a titan of a weapon in a hummingbird-sized frame.
