Quoting this directly from my skill tree.
Conveyance
"Rejuvenate has a 100% chance to grant Conveyance, which increases the effect of your next healing ability:
Benevolence: Force cost reduced by 50%
Deliverance: Activation time reduced by 1 second
Healing Trance: Critical chance increased by 25%
Salvation: Force cost reduced by 30%"
That is with 2 points put into the talent. So if you have 2 points in the talent, cast Rejuvenate, it should give you conveyance. Then your next deliverance will have the 1 second off.
