Feedback (priest ability)

Feedback is a Shadow-based short-lived buff. As long as it is active, any spell cast against you will burn enemy's mana and damage them. It is only available to Human Priests.

In the third war, Feedback was an ability used by human arcane towers and blood elf Spellbreakers with similar effects on mana using units.

Tips and tactics

 * Although Feedback is a highly situational spell (both due to the duration and cooldown), it can be extremely useful in some situations. For example, a mage's Pyroblast can be successfully countered by quickly casting Power Word: Shield and Feedback.
 * This spell appears to proc on every tick of a channeled spell. Because of this, using it when attacked by channeled spells is a very fast and mana efficient way to hurt an enemy caster's mana, channel time, and health.
