  • When used by HarrowIcon272.png Harrow or HarrowPrimeIcon.png Harrow Prime, the Knell Prime's Magazine size is increased by 1 round, for a total of 2 rounds.
  • Death Knell adds a flat Critical Multiplier by 0.5x and a flat status chance by 20%. It also grants unlimited ammo. The buff lasts for 2 seconds and can be refreshed.
    • Critical Multiplier and Status Chance bonus can stack up to 3 times. When the buff times out, one stack is lost and the buff duration resets.
    • Critical Multiplier bonus is calculated as:
      Crit Multiplier = 2 × (1 + Crit Damage Mods) + 0.5 × Number of Stacks
    • The buff triggers only on Headshots, and not other weakspots, such as the backpacks of most MOA variants. Similarly, shooting weakspots generated by either Sonar130xDark.png Sonar or Mod TT 20px.png Detect Vulnerability in places other than heads will have no effect either.
    • Headshots on corpses can proc Death Knell.
    • Individual Multishot bullets can proc Death Knell and can generate max stacks instantly from a single shot.
    • As an indication that this buff is active, the scope design while zoomed in will evolve, as well as showing the Death Knell buff in the UI.
      • The scope shows a 1.5x, 2.0x or 2.5x Critical Multiplier for the number of stacks respectively. However this does not represent the actual buff.
