History of Wavesplitter

The Wavesplitter is a Void Exotic Trace Rifle made by Omolon, which uses focused sonic waves to superheat electrons into a beam. Its intrinsic Harmonic Laser cycles damage through three power levels during sustained fire; picking up an Orb of Power locks it at maximum.

Acquisition

Exotic engrams (extremely rare world drops), PvE and PvP drops, and Xûr when it is in his rotation.

Catalyst

The catalyst adds Detonator Beam (explosions around the target during sustained damage) and Attrition Orbs (Orbs of Power from sustained damage). Defeat 500 targets to masterwork it. It drops from Vanguard Ops, Crucible, Gambit or Exotic Order payouts per ProGameTalk.
