Enemy Resistance

Diablo II Notation Basic Class Skill Item Ally Quest Area Monster Tale Attribute Unit Animation Attack Damage Death Crushing Blow Deadly Strike Enhanced Minimum Maximum Adds Damage Damage + % Damage to Demons to Undead Magic Fire Lightning Cold Poison Skill Damage ATD/ATLD DR/MDR Resistance Maximum Enemy Resist Sunder Immune Absorb Enemy Fire Resistance Enemy Lightning Resistance Enemy Cold Resistance Enemy Poison Resistance -% Enemy Resistance decreases enemy resistance, but only if < 100%. It only applies to any damage applied by the user. When present on two weapons, the percentages of both are summed and applied to the enemy. [1] [2] In LoD it does not apply to damage applied by pets summoned by the user (including sentry traps), with the sole exception of Hydra. In D2R it is inherited by the following pets: Hydra (fire), Blade Sentinel (fire, lightning, cold, poison), Charged Bolt Sentry and Lightning Sentry (lightning), Wake of Fire and Wake of Inferno (fire), Death Sentry (fire and lightning). In data files this stat is called "passive pierce" (for example passive_fire_pierce). Decreasing enemy resistance can have a significant impact on damage, particularly after removing an immunity. For example, casting level 7 Lower Resist decreases Resist 100% to 90%, so the immunity is removed but only 10% damage is applied; -15% Enemy Resistance decreases it from 90% to 75% to increase damage from 10% to 25%, multiplying it by 2.5 (25/10); another -25% Enemy Resistance decreases it from 75% to 50% to increase damage from 25% to 50%, multiplying it by 2 (50/25) or 5 (50/10) overall. The table below lists multipliers of damage (or effective life) as resistance decreases (or increases): Resistance Initial Final 0% 25% 50% 75% 80% 85% 90% 95% 0% 1.00 1.33 2.00 4.00 5.00 6.67 10.00 20.00 25% 1.33 1.00 1.50 3.00 3.75 5.00 7.50 15.00 50% 2.00 1.50 1.00 2.00 2.50 3.33 5.00 10.00 75% 4.00 3.00 2.00 1.00 1.25 1.67 2.50 5.00 80% 5.00 3.75 2.50 1.25 1.00 1.33 2.00 4.00 85% 6.67 5.00 3.33 1.67 1.33 1.00 1.50 3.00 90% 10.00 7.50 5.00 2.50 2.00 1.50 1.00 2.00 95% 20.00 15.00 10.00 5.00 4.00 3.00 2.00 1.00 Of course it can result in Resist < 0% as well, decreasing it to the floor of -100%.
