Acid retal build (with retal added to attack)? Something with Righteous Fervor, for example…
Are you kidding me? Had you not seen that “6% of attack damage converted to health for AAR”? That bonus alone is worth more, than all Reaper of Accursed bonuses together.
First, Pulsing Shard is a mandatory, BUILD-ENABLER item for lightning AAR (who use Aetherbolt Pendant for amulet slot)! It’s BiS for fire AAR either, and is also a very solid option for any other AAR build.
Here’s a link to my lightning AAR build/guide with it:
