When Struck

% 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.

Skills are cast in a variety of ways:

User	User Location	User to Attacker	Attacker Location
Fade Venom Cyclone Armor Bone Armor Blaze Enchant Teleport Chilling Armor Delerium	Slow Missiles Howl Poison Nova Static Field Frost Nova Nova	Twister Tornado Bone Spirit Holy Bolt Charged Bolt Chain Lightning Glacial Spike	Mind Blast Curses Bone Prison Fist of the Heavens Fire Wall Meteor Blizzard Hydra
