NotesEdit
- One main blueprint is required to reach the Rank of Clearance: Odima with the Necraloid.
- With Punch Through modded on the explosions from primary fire occur on the first object hit rather than where the projectile visually detonates, unlike launcher weapons.
TipsEdit
- The strong initial recoil can be reduced with Stabilizer.
- Naturally effective against Cambion Drift Infested, especially when building for Corrosive and Heat as the tougher enemies have tough Infested Sinew armor as well as being immune to Viral procs that would normally allow for increased damage.
- Despite not being able to equip Tactical Reload, the Synth set bonus will still reload the magazine whilst holstered.
BugsEdit
- Using Alternate Fire disables ammo pool for a moment. If Trumna is swapped during this period, it will prevent Trumna from reloading while holstered by Synth set mods.
TriviaEdit
- Trumna is a Polish word for coffin, coming from the Middle High German word 'Truhe' which means chest.
- Trumna produces a "ping" sound resembling the M1 Garand rifle's when reloading.

Patch HistoryEdit
- Removed Punch Through on the Trumna Alt Fire projectile.
- The main feature of the Alt Fire is the radial attack on each bounce, and Punch Through can make it disappear through geometry. Disabling on the projectile only allows Punch Through to be used with the Primary Fire without affecting the Alt Fire.
- Tweaked reload sounds of the Trumna.
- Fixed Trumna local firing sounds playing for Clients.
- Fixed missing Trumna Alt Fire animations.
- Introduced.
