Damage Reduced

• Damage Reduced applies to any physical damage remaining after Bone Armor and then Energy Shield have been applied.
• Does not apply to Crushing Blow damage or Sacrifice damage to self. [1]
• Effectiveness is reduced when applied to physical damage applied by the following missile attacks:

Source	Damage Rate
Diablo Firestorm	41/1024 (~1/25)
Diablo Lightning	82/1024 (~2/25}

[2]

• When DR completely negates pure physical damage, it does not matter if Amplify Damage or Decrepify then reduce Damage Resist/Reduced by %, since there is no damage to which DR % can be applied.
• It is possible to equip enough DR to significantly reduce or negate non-critical physical damage of normal monsters even in Hell, particularly when combined with -% Damage. However, this is not the case when significant +% Damage is applied by skills or Champion or Unique monsters, particularly when DR % is subsequently reduced as well.
• When an attack applies both physical damage and magic, fire, lightning, cold or poison damage and DR > physical damage, the excess is applied to the sum of non-physical damage after Resist % and Absorb have been applied [3] [4] (only applies to first frame of poison damage). [5]
• Attack applying 50 physical damage, 50 fire damage and 50 lightning damage to a target with DR 100, Fire Resist 50%, Lightning Resist 50% and +20 Lightning Absorb would apply no physical damage (50-100 = -50), 50 fire damage and 30 lightning damage (80 total) before excess DR (-50) applied: this would result in 30 (80-50) damage before 20 healing from +20 LA, which would result in just 10 net life loss.
