  • This mod can be purchased unranked from the Void Trader Baro Ki'Teer for Credits64100,000 and PrimeBucks350. 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 20pxHeavy 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 20pxCollision Force to provide a 285% total increase to Impact b 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 Impact b Impact damage exceeds 60% of total weapon damage. This does not take damage type multipliers into consideration.
  • Compared to Mod TT 20pxPrimed 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 Impact b Impact damage. It terms of mod slot efficiency, it is simply inferior.
  • AtlasIcon272 Atlas' Landslide130xDark Landslide and BaruukIcon272 Baruuk's SereneStorm130xDark Serene Storm benefit from this mod. ValkyrIcon272 Valkyr's Hysteria130xDark Hysteria benefits more from Mod TT 20pxPrimed Pressure Point.
