I haven't properly tested out this build.
Predominantly to be used for group healing in dungeons.

1st Bar - Restoration Staff.
I plan to use this primarily for bosses. Ensuring to keep Combat Prayer and Ritual Retribution up at all times. Luminous Shards to deal damage and help the tank keep stamina up. Rapid Regeneration is interchangeable - potentially for chaneled focus/siphoned spirit/mystic orb/inner light aka something to help restore magicka. And of course Breath of Life for panic heals.

2nd Bar - Destruction Staff
To deal with groups of enemies/deal additional damage to bosses.
Elemental Blockade, Puncturing Sweeps and Reflective Light is fantastic for AoE. Repentance I find comes in extremely useful when dealing with hoards of enemies but is otherwise useless when dealing with bosses. So I interchange it with Purifying Light/Radiant Oppression to help the dps.
