History of Blades

Blades is a Prismatic Lens triumph from the Season of the Splicer era (Season 14). Completing it discovers the lens and unlocks a Focused Umbral Engram at the H.E.L.M.

How to complete

Defeat enemies with Swords. Two sources agree on this objective.

Reward

The Blades focus is described as containing a random Sword. Each Prismatic Lens only needs unlocking once. Umbral Engram focusing is a seasonal system and may not work the same today; I could not confirm current availability or which seal this belongs to.
