UNIQUE Passive: Dealing spell damage deals bonus magic damage over 3 seconds (1.5 seconds for multi-target or damage-over-time effects) equal to 5% of the target's current Health (max 300 damage to monsters). If the target is slowed, stunned, taunted, feared, or immobilized, bonus damage is doubled.

(Magic Penetration: Magic damage is increased by ignoring an amount of the target's Magic Resist equal to Magic Penetration.)
