I am currently using two different Ritualist builds:
Offensive Spirit build
Healer Build
Both can be used on character or hero. Currently I use the Healer build on my char, and the offensive spirit build on my Rit hero, which works very well. Combine party with SS or MM hero, and you can't die.
The Offensive Spirit build uses the following skills:

Destruction
Essence Strike
Gaze from Beyond
Pain
Bloodsong
Generous was Tsungrai
Agony
Flesh of my Flesh
communing 11
channeling 11
spawning 11
The Offensive Spirit build uses the following runes/insignias:
Rune of minor communing magic.
Shaman's insignia (2x)
Rune of Minor or Major Vigor
The Offensive Spirit build works well with the following Green weapon:
Synn's Staff (requires 9 Channeling magic)
The Healer build uses the following skills:

Weapon of Remedy (Elite)
Mend body and soul
GhostMirror Light
Spirit Light
Protective was Kaolai
Life
