It's funny when doing the realm shift build I still hated how little damage I was doing and found out I could still usually sneak hits in on the sisters even without triggering the realm shift, so dumped the realm shift wrist and waist armor and went back to the full Lunda set. Even managed to take the triple berserkers out without equipping my Vanaheim amulet set that added extra damage onto status affected enemies; still had my realm shift relics equipped that were useless without realm shift armor.
Lunda's chest piece with the Vanaheim amulets and the dragon wrist and waist armor is really good in the game though. Instead of getting +40% melee attack onto poisoned enemies you get +50% shield attack without needing the poison plus whatever you inflict on the enemy with poison from your shield. Really eager to see how this build holds up to the Valkyrie Queen once I get there.
