Confidence Ritual

Confidence Ritual is a Witch Doctor passive skill, unlocked at level 60. It was added in patch 2.3.

In-game
This skill works similarly to Wizard passive skill Audacity: it multiplicatively boosts all damage taken by enemies as long as they are within certain distance of the Witch Doctor.

For pet attacks, the distance is calculated from the Witch Doctor, not from the attacking pet.

Unlike other distance-based Witch Doctor skills, this one does not benefit from increased gold / Health Globe pickup radius.

Trivia

 * Intentionally or not, the icon design of this skill is identical to that of Audacity.
