predcon: Do you know how to access this menu in the official modules?
Ralackk: No sorry, not tried messing around with those yet.
Do you know if all merchants carry a "Merchant" label or something in their character class, and if so, would it be possible to modify the DEBUG Dialogue script to apply to any Merchant class character?
The other solution would be to make up your character using the Virgil DEBUG script in the main module, and export it to the "Pick Character" menu that you get when starting a new game. Unfortunately, Arcanum doesn't provide for importing/exporting of characters in the way that Sacred does, so one would have to use a third-party tool.
