Killing Bl0w is a tier 1 skill in Zer0's Bloodshed skill tree. It gives a massive damage boost to melee attacks on enemies with low health.

  • An enemy is considered to have "low health" at 30% or less health.
  • Killing Bl0w is very useful against bosses, badass enemies or other large enemies. Often, it can effectively remove the last 30% of their health with one melee attack, given enough investment.
    • However it is of much less use against the smaller, common enemies, as most of the damage would be wasted at the point the ability would trigger.
  • This bonus scales total melee damage, and is multiplied after every other bonus has been applied.
  • Depending on Zer0's build, it may not be necessary to spend a full 5 points in Killing Bl0w. For example, when performing the Execute attack using a good quality Love Thumper shield, a +30% melee damage relic and a +200% melee damage Vladof Rapier assault rifle, on most enemies (even Super Badasses and most unique enemies) there may be no effective difference between rank 3 and rank 5 of this skill. With a Ninja class mod that adds to Killing Bl0w, investing a single actual skill point may be sufficient.
