The Equalizer is well known to be bugged, so while wearing it in your offhand, it gives its bonuses to your main hand as well. Combine that with its protective bonuses and you have, alongside Faeyr, arguably the best offhand weapon in SoA.
I fancy Angurvadal or Spectral Brand in my offhand as well. Immunity to level drain is never wrong, and they both have other good offhand abilties as well, combined with some extra damage.
The other good ones have kinda already been mentioned.
