Upgraded in this order -
Enlightened Healing
Rejuvenating Chant
Transcendant Blessing
Ancestral Aegis
Umbral Ritual
Runic Talisman (now a master1)
Eidolic Mettle
Ursine Prophet
Prophetic Shield
The last half of those are just spells I upgraded because we have a lot of luck with getting rubies off of raid mobs, so rubies are relatively cheap to come by.
