Hybrid of Dark Chalice and Classic Chalice.
Taking the best bits of both, this is a quite interesting build.
Play Ephemeral Wisps early and often, and always Chalice them first, followed by Heirloom Seekers. Hidden Road smuggler got buffed for Chalice, just like Jennev Merchant did a bit ago, and don't be afraid to Harsh Rule, especially if you have 2+ buffed Wisps.
