Detect Lesser Invisibility

Detect Lesser Invisibility was a level 26 Warlock buff that allowed one to see units cloaked by invisibility. There were three warlock invisibility detection spells, of which this was the lowest. It did NOT allow you to see stealthed units such as rogues, instead letting you able to detect enemies like Eyes of Naxxramas and the Unseen.

This ability and Detect Greater Invisibility were removed in Patch 2.0.1, leaving only Detect Invisibility.
