Thrax enemies are abundant in Mobile Defense and Void Cascade missions.
The Zariman Arcane drop is considered as a mod drop, and is thus affected by The Steel Path and Mod Drop Chance Booster.

Damage bonus is additive to mods.
At all ranks, it will take 40 Heat procs to reach the maximum damage bonus.
The bonus damage is applied on all damage types present in the secondary, and not just Heat damage.
Stacking Cascadia Flare does not require the Heat proc to come from the secondary: it can come from Warframe abilities such as Ember's ability kit and Protea's Blaze Artillery, or any weapon or companion that can proc Heat - even if the secondary is holstered.
- Unless one is riding Merulina, in which case, only procs from the weapon itself will count.
Unlike other weapon arcanes, Cascadia Flare stacks expire all at once after 10 seconds of no procs, rather than only 1 stack every 10 seconds.

With high fire rate weapons such as Spectra, Cascadia Flare's max stack can be reached rather quickly despite its tendency to lose all its stacks upon expiry.
Equipping a sentinel with a high-status companion weapon such as Verglas — modded for viral and heat, fire rate and multishot — can effectively help keep the stacks of Cascadia Flare maxed.
Works well on secondaries with innate Heat damage and high status chance such as the Atomos, Hystrix ( Prime) with Heat Quills, and Tenet Cycron, as long as Heat is included among the listed elemental damage and not its derivatives such as Gas.
- Also works very well with weapons that possess a base secondary elemental damage type and high status chance such as the Synoid Gammacor and Kompressa when combined with Primed Heated Charge, as long as the added Heat is included as a damage type.
