The passive armors should have phased shield ability.

Weapons that skip armor, or ship shields will negate the bonus effects of the passive armor, and are NOT generally reccommended!

Do you really want a weapon that will turn the shadow's armor into cheap inert junk?

You can use the Quad-to-shields damage type (and its variants) to tweak the penetration ability of your weapon much more effectively.

Quarter damage = 80% absorbed (max 4x crystalline ability)
Half damage = 66% absorbed (max 2x crystal ability)
normal = 50% absorbed (max 1x crystal ability)
Double = 33% absorbed (max 1/2 crystal ability)
Quad = 20% absorbed (max 1/4 crystal ability)
