wouldn't sun&moon trigger SS's bonus twice? in this case taking weapon of aggression would be best.
I played around with an SS Build the other day...I like Weapon of Agression, and it was surprisingly easy to keep up:
Rt/P:
[skill]Spirit's Strength[/skill][skill]Sight Beyond Sight[/skill][wiki]Weapon of Agression[/wiki][skill]Splinter Weapon[/skill][skill]Wielder's Strike[/skill][wiki]Holy Spear[/wiki][skill]Blazing Spear[/skill][skill]Merciless Spear[/skill]
Daggers/Sword would probably be better for AB mind you, I'm yet to try with daggers.
Another AB build I found fun was:
[skill]Grasping was Kuurong[/skill][skill]Ancestors' Rage[/skill][skill]Spirit Rift[/skill][skill]Essence Strike[/skill][skill]Resilient Weapon[/skill][skill]Weapon of Shadow[/skill][skill]Mend Body and Soul[/skill][skill]Bloodsong[/skill]
The above could solo-cap most shrines. I never managed to solo the Ele Shrine with it though

The idea was to pre-cast Kuurong, so that if a Sin thought I was an easy target I could drop them, knocking him over, and cast Weapon of Shadow on myself before I finished him off.
With shrines, similar idea...Pre-cast Kuurong, stand just out of range of shrine, cast Resilient Weapon / Weapon of Shadow, Cast Spirit Rift, run in and drop Kuurong, cast Ancestor's Rage, repeat as necessary.
Finally, I ran a dual build with another alliance member a while ago:
[skill]Offering of Spirit[/skill][skill]Cruel was Daoshen[/skill][skill]Ancestors' Rage[/skill][skill]Weapon of Warding[/skill][skill]Mend Body and Soul[/skill][skill]"Make Haste!"[/skill][skill]Resilient was Xiko[/skill][wiki]Agony[/wiki]
One of us used Agony, while the other used Destruction. Pre-cast Daoshen as much as possible and keep using "Make Haste!" on each other (at 6 command it can be kept up continually)...Idea was to run up to a shrine, cast spirits just out of range, pull NPCs/players out a little into range of Agony, run up, re-cast Daoshen (causing you to drop your current Daoshen), Drop the new Daoshen, use Ancestor's Rage.
It worked really quite well ^^
