I made a video of one of the builds I'm min-maxing this league, an Abyss Charge stacking Pathfinder. It's not the strongest build in the world but it uses some cool interactions and I've been able to do most content I've thrown at it (Ubers, Wave 15 simulacrum, T17s, etc.). The build has 100% uptime on 15 spirit charges for a total of 225% of phys as extra elemental damage, which is the main way we scale our damage.
