The fan-favorite Trumna assault rifle has finally been primed inWarframe.This massive rifle fires explosive rounds that decimate foes in seconds. Get enough kills with the Trumna, and you’ll charge its devastating alt-fire, clearing entire rooms of enemies with its ricocheting, explosive projectile.
Making this weapon clear Star Chart and even Steel Path content isn’t too difficult, but you’ll want the best builds possible to take this in Steel Path Circuit and Elite Archimedia. Today, we’ll be looking at the Trumna and its prime variant, showcasing its acquisition methods, quirks, and some excellent build you’re able to use in Steel Path and beyond.

The Trumna is a slow-firing, full-auto assault rifle that fires explosive rounds. It features excellent critical stats, high base damage, and solid status chance for a rifle. What keeps the Trumna in check is its horrendous reload and fairly slow fire rate. If you can fix these issues with mods, you’ll have a monstrous rifle for most content.
Both the Trumna and its Prime variant have asecondary fire that launches a ricocheting projectile, detonating with each impact.This can carpet bomb an entire room of enemies, dealing millions of damage per explosion. Charging the alt-fire requires a total offive killswith your primary fire. Kills with the alt-fire can’t charge the alt-fire.
Trumna Builds
We will be sharing two builds today: one for a starter Trumna Prime configuration and a more min-maxed build for the Trumna Prime. This weapon is a typical critical rifle, so building it for critical chance, critical damage, and elemental damage is highly recommended. You’ll also want something in your loadout that helps mitigate the weapon’s atrocious reload, either through Warframe abilities or Trumna mods.
Riven Mods
Trumna Rivens have a fairly low disposition, so you’ll need a perfect roll to outperform most standard mods. Some good stats include Critical Chance, Critical Damage, Multishot, Fire Rate, andelemental damage types.
Variant
Trumna Prime
If you’re using the standard Trumna, you can drop Primed Cryo Round for Rime Rounds.
This build is a standard critical configuration for the Trumna Prime. We useSerrationto scale our base damage since we don’t have many damage types toscale Galvanized Aptitude. If you own it,Primary Mercilessis also great for lowering your reload speed while further scaling your base damage. For multishot, you can’t go wrong withGalvanized Chamber.
Critical damage scaling isn’t anything special here.Critical Delaygives you the most critical chance without requiring you to meet any niche conditions. Throw onVital Sensefor more critical damage. Use your remaining capacity on an elemental combo of your choosing. The build above uses Blast, but feel free to swap this element to suit the enemies you’re facing.
Now that we have some Forma on the weapon, we can throw on some much stronger mods to scale the Trumna’s damage. We replace Serration withGalvanized Aptitudeso we can scale our base damage more aggressively. We also now useRadiated Reloadto give the Trumna some Radiation damage and a sizable boost to its reload speed. When paired with Primary Merciless, you’ll now reload in a much more reasonable 2.4 seconds.
We also useVile Accelerationto drastically increase the weapon’s fire rate, making it function much better as a typical assault rifle. You should also have enough capacity to addStabilizerto the Exilus slot, drastically reducing the gun’s visual recoil. If you want to scale the damage even further, throw on another Forma and use Primed Cryo Rounds to aggressively scale Viral or Blast damage. This will limit your elemental combinations, so this might not be worth it if the Trumna is your daily driver.
