Hello
Would using a "Check" character to show the stash and gold before starting the run with another character work?

Path of Exile 2

Basic Category Rule Set and Interim Rules for Early Access PoE2

Lolliprop

PoE2 Speedrun Leaderboards will begin accepting runs with 3 categories on 1/2/25: A1 Pts, A3 Pts, and A6 Pts. These runs will require completion of any quest/optional encounter that awards a permanent buff either to stats or passive points. You will also be required to ascend in the A3 (at least 2 ascendancy points) and A6 (at least 4 ascendancy points) runs.

There is still on-going discussion for mods about allowing for some form of Any % runs or Geared runs and how to implement any such runs. If you are interested in a run type that is not listed, please visit the forums and create a post about the category you are potentially interested in
