I would suggest reading tooltips before starting a thread like this.
As per the tooltip:
"You have a 10% chance for your Shadow Word: Pain and Mind Flay spells to grant you a Shadow Orb each time they deal damage."
The talent Harnessed Shadows [2/2]:
"Increases the chance for you to gain a Shadow Orb when dealing damage with your Mind Flay and Shadow Word: Pain by 8%, and you have a 100% chance to gain a Shadow Orb when critically hit by any attack."
