  • This mod can be purchased unranked from the Void Trader Baro Ki'Teer for Credits64.png 100,000 and PrimeBucks.png 350. Note however that Baro Ki'Teer's stock changes with each appearance, and may not have this item available at every time.


  • Primed Heavy Trauma is essentially the Mod TT 20px.png Heavy Trauma mod with Legendary rarity and 5 more ranks. It is considered the same mod as its Rare counterpart, and thus both mods cannot be equipped together.
  • Can be combined with Mod TT 20px.png Collision Force to provide a 285% total increase to DmgImpactSmall64.png Impact damage.
  • Compared to a base elemental mod (+90%) in terms of raw damage, Primed Heavy Trauma becomes more effective at rank 9 when a weapon's DmgImpactSmall64.png Impact damage exceeds 60% of total weapon damage. This does not take damage type multipliers into consideration.
  • Compared to Mod TT 20px.png Primed Pressure Point, they share the same % bonus, but Primed Heavy Trauma uses 12 mod capacity instead of 14, making it more cost efficient only if more than 85.7% of a weapon's base damage is DmgImpactSmall64.png Impact damage. It terms of mod slot efficiency, it is simply inferior.
  • AtlasIcon272.png Atlas' Landslide130xDark.png Landslide and BaruukIcon272.png Baruuk's SereneStorm130xDark.png Serene Storm (without Reactive Storm augment) benefit from this mod. ValkyrIcon272.png Valkyr's Hysteria130xDark.png Hysteria benefits more from Mod TT 20px.png Primed Pressure Point.
