Flare

Flare is a hunter ability that reveals any stealthed, hidden or invisible units within 10 yards of the targeted area for 20 seconds.

Tips and tactics

 * If you have a suspicion there's a hidden or invisible unit in an area, you can Flare to reveal any of them. This can be especially useful in PvP or in places where you know there are stealthed mobs, such as the western wing of Dire Maul.
 * Can be useful for finding invisible creatures, such as the elite hunter pets in Pandaria, eg. Patrannache.

Trivia
