Thanks for the response. I wish there was a better self heal skill for Templars besides Healing Ritual. The time it takes to cast often results in me taking more damage than I can heal.Yes, it can heal you. Yes, it can heal you or an ally. Any spells which affect allies affect you too. However, Rushed Ceremony says 'lowest health ally'. At times this may be you and it may not. The spell is a "smart heal" in that you cannot choose the target. It auto selects the lowest health target in range and heals that target. If you're trying to use it in group as only a self heal, you're gonna be hung out to dry a few times. If you're trying to use it as an "oh crap" burst heal for any ally in need, then it can be useful. The only way it will work as a solo heal reliably is if you are completely alone...playing solo and away from other players. Even if they aren't in your group, this heal can and will reach out to nearby players who happen to be missing more health than you.
The morph Breath of Life allows it to hit 2 additional targets for a total of 3. This can definitely increase your chances of being one of the recipients.
I'm glad I've put points in this skill; I'm using Breath Of Life. It usually does tend to heal me as well, and fairly well.Don't get me wrong. You can use Rushed Ceremony for self heals. You just have to keep in mind that it is not always "smart" enough to prioritize the caster.
