I would use :
2x Orbs : 20% crit dmg in slot
Suit , Boots , Gloves dlb amped or 1 slot amp or amp craft + slot
Helm : 20% crit dmg in slot
2x Rol + 2
2x BOS+4
If you extend the orbs and the helm => 30 + 30 = 60% crit dmg
Rol + 2 => 30% crit rate
Suit , boots , gloves amped + bos+4 => 21% + 2x 6% = 21 + 12 = 33% m. amp , and if both braces are sloted with amp you get and additional 6% amp => 39% m. amp
Hope it helps you
