When Struck

Diablo II Notation Basic Class Skill Item Ally Quest Area Monster Tale All Skills Fire Skills Skill bonus Oskill Aura Equipped Charges Charged suffix Chance to Cast On Attack On Striking When Struck When You Die Kill an Enemy Level-up Chance to Cast When Struck is applied whenever the user is hit by a melee attack (excluding charging Claw Vipers and Reanimated Horde), a missile attack applying weapon or monster damage, persistent traps or fires, or exploding barrels. Not applied by missiles which only apply their own damage or skill damage. Most of the applicable missile attacks are intuitive (the user is hit by a visible arrow, bolt, dart, javelin, quill or throwing weapon), but others are less obvious: Tainted lightning orbs Skeleton Mage bolts Lightning Spire bolts Willowisp lightning bolts Demon Imp fire bolts Claw Viper missiles Succubus and Stygian Fury bolts Not applied by returned damage or death explosions.
