Shaman/Skyseer Healer Absolution Build

Hi :)
I've put my hand on a decent absolution so i leveled a shaman to have it as a healer class, i would like to get a build that focus mostly on healing in grind parties (if its possible to do some damage it can be nice but its not mandatory)
cost doesn't matter but i would prefer a build without crafteds. archetype doesn't matter aswell.
