I use saracen's ammy for the extra 10% chance to amp damage, and for rings, I use two nagels. I used to use two BK rings, but in full IK, two nagels can put you over the 400% MF soft cap with gheeds charm and ptopazes filling the IK helm and body. I sub a nagel for a raven frost when I want to do the act5 portals and rarely die.
