Secondary Irradiate is a rare Secondary Arcane that spreads damage to nearby enemies when hitting targets affected by Radiation, making it excellent for crowd control.
It pairs best with secondaries that consistently apply Radiation, allowing players to deal area damage while keeping their primary weapon focused on single-target precision.
Acquiring this Arcane early enhances secondary weapon performance, boosting hybrid and status-focused builds for high-level missions without relying on rare drops or luck.
How To Get Secondary Irradiate?
Secondary Irradiate can be purchased from Roathe at La Cathédrale in the Sanctum Anatomica on Deimos for 5 Maphica.
It cannot be farmed in missions, obtained from relics, or traded for in-game currency, so buying it is the only reliable method to secure it.
This straightforward approach allows Tenno to plan their Arcane upgrades, gaining immediate access to the crowd-control potential once they have enough Maphica.
Secondary Irradiate Effects
Secondary Irradiate activates when hitting enemies with 10 stacks of Radiation, spreading a portion of damage to nearby foes starting at 80% at rank 0.
As the Arcane ranks up, the spread damage increases to 180% at max rank, making it more effective in crowd-heavy encounters and larger mission areas.
The radius also grows with rank, from 4.5 meters to 7 meters, allowing multiple enemies to be affected without direct hits and improving secondary weapon efficiency.
Spread hits inherit the original status effects, trigger weapon on-hit effects, and benefit from status damage, but they do not apply headshot or weakpoint.
Secondary Irradiate Farming Tips
The fastest way to farm Maphica is by looting as many crates and rewards as possible while running The Descendia missions.
Always be ready to extract if the mission becomes too difficult, as dying will fail the run and forfeit any Maphica you’ve collected.
The quicker you gather Maphica, the sooner you can purchase Secondary Irradiate, unlocking its benefits for your secondaries without delay.
Verdict
Secondary Irradiate is a powerful Arcane for secondaries that consistently apply Radiation, enhancing crowd-control and spreading damage to multiple enemies.
Efficient Maphica farming lets you acquire it faster, giving your secondaries immediate improvements in damage and status application.
Equipping this Arcane boosts hybrid and status-focused builds, making it a worthwhile investment for both solo and squad play.
