    • Obsidian Cleaver increases
      Black Cleaver
      's stats by 20 Attack Damage and 150 Health.
  • Both passives trigger on both basic attacks and on any abilities that deals physical damage.
  • Physical damage over time abilities will apply one stack on every tick.
  • On-hit effects, which is different from on-hit abilities, do not apply an additional armor shred stack.
  • The armor reduction stacks from The Black Cleaver apply only to enemy champions. They will not affect minions, neutral monsters or structures such as turrets and inhibitors.
  • Pets that deal physical damage will apply stacks, even if they don't apply on-hit effects or spell effects.
  • The very first instance of physical damage does not get the benefit of the armor reduction. The physical damage dealt is calculated first, and the debuff is applied after. This means the full benefit of the reduction is seen on the seventh hit, after all six stacks have been applied.
  • Armor reduction and penetration effects stack.
  • When combined, The Black Cleaver and
    The Obsidian Cleaver
    will apply 2 stacks per instance of physical damage, instead of 1. This is because the unique passives are not named and they are not the same item. However, the two items share the same maximum stacks.
  • Multiple instances of physical damage applied at the same time will only apply one stack.
