anyone know anything about shockwave?

i know stats/skills but gear is the hard part..

1: does ED% from wep add to shockwave?

2: does ED% from armor add to shockwave?

3: do 40/15s help shockwave dmg?

4: does cb, ow, ds help shockwave?

5: would grief be good for wep? or 5os rune master with 5x ber's (cb)?

6: oak sage (lots of life) or HoW (more dmg/ar)?

can anyone also suggest remaining gear for rich?
