[Vulcax] has a hidden, 0.1 damage, innate magnetic 5.0m AoE with base 20% status chance. This build optimizes this hidden feature to act as a status primer, with weaker stacking than [Helstrum] but with larger AoE. This build gives a 44% status chance for Radiation, Viral, or Magnetic procs in a 7.2m AoE. Equip [Fired Up] to your sentinel for AoE heat procs.

[Vulcax] also has base 20% Crit Chance, able to hit 50% crit chance with just [Point Strike], which enables a +1.2x Crit Damage buff for your Warframe's weapons by [Tenacious Bond].

Finally, Vulcax is hitscan with perfect accuracy. This makes it extraordinary for open-world combat with long range sentinels (e.g. [Diriga]'s [Calculated Shot] at 70m).

For Riven mods, aim for Reload Speed, Status Chance, Crit Chance (only if 150% or more), and Magazine Capacity (only if 50% or more).
