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 Physical Immunity Sundered Magic Immunity Sundered Fire Immunity Sundered Lightning Immunity Sundered Cold Immunity Sundered Poison Immunity Sundered Reduces immune monsters' resistance to 95% for the particular element only. D2R only [1] Applied before any other source of Enemy Resistance. Lower Resist, Conviction and Cold Mastery are applied with 1/5 effectiveness. Other skills and Enemy Resistance items are fully effective. Does not work if the enemy is not immune. Works for the player and its pets: Valkyrie (physical, fire, lightning, cold, poison), Hydra (fire), Raise Skeleton (physical), Clay Golem (physical), Raise Skeletal Mage (fire, lightning, cold, poison), Blood Golem (physical), Iron Golem (physical, magic, fire, lightning, cold, poison), Fire Golem (fire), Revive (physical, magic, fire, lightning, cold, poison), Raven (physical), Poison Creeper (poison), Summon Spirit Wolf (cold), Summon Dire Wolf (physical), Summon Grizzly (physical), Blade Sentinel (physical, fire, lightning, cold, poison), Charged Bolt Sentry and Lightning Sentry (lightning), Wake of Fire and Wake of Inferno (fire), Death Sentry (physical, fire, lightning), Shadow Warrior and Shadow Master (physical, fire, lightning, cold, poison), Summon Goatman (physical), Summon Tainted (physical, fire), Summon Defiler (physical), Bind Demon (physical). Does not work for hirelings or party members. Does not work against enemy players. Sunders of the same element do not stack (for practical purposes - see below). In data files this stat is called item_pierce_<element>_immunity (for example item_pierce_fire_immunity). Actually it reduces the enemy resistance by a set value, but not to lower than 95%[2]. In the unmodified game all Sunder sources have this value set to 300. While it's enough to reduce resistances of most immune monsters to 95%, there are a few outliers[3]: Gargoyle Trap (1000% cold resistance) Fire Tower (1000% poison resistance) Lightning Spire (1000% poison resistance) Barricaded Door (1000% poison resistance) Barricade (1000% poison resistance) Barricaded Tower (1000% poison resistance) Prison Door (1000% poison resistance) Catapult (1000% poison resistance) So, technically, Sunders of the same element do stack, but in practice it's not worth it, given that the Sunder sources also impose negative resistance on the player, which also stacks. A Gargoyle Trap stays Immune to Cold, despite the Sorceress having Cold Rupture in her inventory. A Gargoyle Trap with cold immunity broken with multiple copies of Cold Rupture, being damaged by a Sorceress using Ice Blast.
