Gain additional damage.Gain +3.5 (+1 per stack) damage when killing enemies.
(stackable) buff stack, which increases damage by 3.5% (+1% per stack) up to a maximum of 10 (+5 per stack). This buff lasts for 7 seconds and is refreshed every time the player kills or deals damage to any enemy.

Notes

• The timer is refreshed every time an enemy is hit, not only when they are killed.
  • The timer refresh requires a non-zero proc coefficient, while a kill does not.
  • The timer refresh also requires the attacked entity to not be on the player's team. While monsters are not expected to use this item effectively, this (most likely) unintended restriction makes the item inefficient for maintaining any kill count, e.g., from killing any allies.
• Once the kill timer expires, every single buff stack is removed at once.
  • 3 seconds before expiring there will be a noticeable beeping sound, indicating the buff is about to end. It will stop once you either run out of time, kill an enemy, or hit an enemy with an attack.
• Once the holder has reached the maximum number of buff stacks allowed a sound is played.
• The item on the survivor's body has a digital display that updates whenever the player registers a kill.
  • While this value tends to be in sync with the number of buff stacks obtained, the display can continue increasing beyond the buff's current cap limit, albeit with a yellowish color to indicate it's above the threshold.
    • If the player then picks up another item stack, the buff stacks will not catch up to the new buff limit, but will still continue increasing with each new kill, maintaining the desync between the buff stacks and item display until this value is reset.
  • Bug: The digital display is supposed to only show kill values between 0 and 999, with the word "GOD" for anything beyond that. However, the code for this is flawed and it always displays a value with a preceeding 0, even for those exceeding three digits.
• Bug: The damage from this item ignores any stat boost from Seekers of the Storm - DLC Content

Tips

  can be a reliable area, albeit location-restricted, where one can rack up kills.
• This item encourages the player to focus on weaker enemies first to build up the damage boost as quickly as possible and then focus on bigger enemies, where continual combat engagement will maintain the accrued damage boost.
• Leaving a non-threatening monster alive in order to hit it occasionally can extend the kill timer when monsters don't spawn fast enough.

Order details:
General Reid,
I examined the devices you sent me and sure enough your unit has been getting WAY too much phencyclidine in their doses. That may explain them trying to eat each other. I’ve lowered the threshold by 15%.

On the bright side, their hand eye coordination has been off the charts. Given the right gun, these soldiers could strike a jet from the ground.

If this trial goes well, and their lungs return to normal, I’ll clear them for duty.
