Figured we should get a few of these posts up to share our knowledge and promote better play.
1: The buff from casting Rejuvenate, Conveyance, is slightly buggy. If you cast a second spell after the first that is modified by the buff, you can use the effect twice. Example, if you cast Rejuvenate, then a Deliverance at 1.5 sec base, and you cast a second Deliverance right after, you can knock it to a 1.5 base cast as well. This works extremely well with Healing Trance, as the buff does not drop until you finish channeling, therefore you can interrupt the Healing Trance with another heal you wish to buff with Conveyance and get the effect twice.
2: Not sure if it is the most effective use yet, but I tend to cast Salvation, then Noble Sacrifice while in the circle.
