Divine Identification
Avenger Utility

Effect: Until the end of your next turn, you know the location of your oath of enmity target, and it grants combat advantage to you, even if you can’t see it.

Divine Identification is an avenger channel divinity power introduced in Unearthed Arcana: Ignorance is Blessed.  It is meant as a substitute for divine guidance.  As an Unearthed Arcana resource, it might not necessarily be canon, and may need to be discussed by the DM first. [Dr398:UA]

It is not rated by character optimization groups. In comparison, divine guidance is rated as excellent, and is much less situational compared to tracking down an invisible target.
