When you think about the best teams you gravitate to teams with the highest overall DPAV. In the world of constant powercreep this is almost a ritualistic activity.
But that isn't always the case. The unfortunate reality is that you cant always expect to have the best options. You inevitably have limited options if you do not spend and must work with what you have.
Almost every unit in the game has their value tied to a "stat", that most people don't talk about and what calcs can't show. In an individual's account, the choices made around overlaps to strengthen a roster is the core aspect of Star Rail's gameplay loop. And having the highest damage alone is not the be all end all as exampled through the game's history.
This is the Acheron Theorem. And if you're still confused? that's fine, because today we will be showing examples of overlaps being almost everything to a team or even an individual unit's perceived and effective power level.
