Steflos Prime GUIDE

Understand Steflos Prime

Useful when…

  • Use its listed attack profile and falloff figures to assess its range for an encounter.
  • Compare its damage, status chance, and falloff interval with standard Steflos.

Projectile profile

Its single normal attack fires at 3 shots per second and lists 480 damage: 285 Heat and 195 Impact. It has 18% critical chance, a 2.2× critical multiplier, and 28% status chance. Projectile speed is listed as 20. Its description says it deals death from farther afar; no projectile growth, hit-extended duration, or Citrine-specific effect is stated for this record.

Range and magazine

Falloff begins at 8 units and reaches 62.5% reduction at 24 units. Standard Steflos's listed falloff reaches a 96.875% reduction at 16 units. Steflos Prime has a 12-round magazine and a 2.4-second reload, and its mastery requirement is 15, compared with 8 for standard Steflos.

Different shotgun mechanics

Arca Plasmor is described as a staggering plasma blast, Astilla Prime fires explosive glass slugs, and Corinth Prime adds remote detonation for its airburst round. These descriptions identify different attack behaviors.

Limitations and tradeoffs

  • Compared with standard Steflos, the Prime lists more damage and status chance, and its falloff reaches a smaller reduction at 24 units.
  • Its listed attack still has 62.5% falloff reduction at 24 units.

Common mistakes to avoid

  • Assuming Steflos Prime inherits standard Steflos's projectile growth or Citrine effect.
  • Assuming the Prime removes falloff or using standard Steflos's falloff endpoint for it.
