Understand Efv-5 Jupiter
Useful when…
- Sustained primary fire using its large magazine
- Using alternate buckshot against targets within its short listed falloff range
What does each fire mode do?
The Auto attack is hit-scan and fires at a listed 7.83 shots per second. It has 21% critical chance, a 2.3× critical multiplier, and 25% status chance, dealing Slash, Puncture, and Corrosive damage. The Buckshot attack is separate: it lists a one-second charge, a 2.1× critical multiplier, and 5.73% status chance. Its listed falloff begins at 5 and ends at 10, with a 0.9921 reduction. The rifle has a 65-round magazine and a 2.5-second reload. The description calls the alternate fire Efervon-laced buckshot, but the detailed profile does not specify a broader area effect.
How should you use it?
The primary mode's high listed fire rate and large magazine suit sustained direct fire; its 25% status chance is also much higher than the alternate attack's listed 5.73%. Use buckshot as a close-range option when the charge is practical, since its listed falloff range runs only from 5 to 10. Avoid assuming that the primary attack's critical multiplier or status chance carries over: buckshot has its own 2.1× multiplier and status value. The rifle has two Madurai polarities listed, which are relevant when fitting mods of that polarity.
What alternatives have different roles?
Dual Viciss is a melee weapon, so it does not replace the rifle's ranged handling. Acceltra Prime is another automatic rifle, described as reloading faster while sprinting and faster still with Gauss. Ambassador switches between charged explosive shots and rapid-fire electrical assault mode.
Limitations and tradeoffs
- Buckshot takes one second to charge and has steep listed falloff over a short range.
- Auto fire and buckshot have different critical multipliers and status chances.
- Mastery requirement is 14.
Common mistakes to avoid
- Do not use Auto mode's 25% status chance or 2.3× critical multiplier for Buckshot.
- Do not treat the Buckshot falloff values as a long-range option.
