Dark Thoughts

Dark Thoughts is a passive level 41 shadow priest ability that grants Mind Flay and Mind Sear a chance to trigger a Dark Thought on targets affected by the priest's damage over time effects. 
When a Dark Thought is triggered, it grants Mind Blast an additional charge. This charge can be consumed to instantly cast the ability without interrupting Mind Flay or Mind Sear.
==Improvements==
The Sepulcher of the First Ones tier set, Habiliments of the Empyrean, features two improvements to Dark Thoughts:
* Darkened Mind (2-set): Casting Devouring Plague has a 40% chance to grant Dark Thought. Casting Searing Nightmare has a 25% chance to grant Dark Thought.
* Living Shadow (4-set): Consuming a Dark Thought causes your shadow to animate after a moment, dealing (125.4% of Spell Power) Shadow damage over 6 sec to all enemies within 10 yards of your target.
==Notes==
*Only one Dark Thought can be active at a time. Dark Thoughts do not stack.
**If a Dark Thought is not consumed within the 10 second duration, the additional charge will disappear when the buff fades.
