If you want other people to play your scenario, it is vitally important that you test it.
Otherwise, lots of people might waste lots of hours playing a scenairo that is unwinnable or otherwise doesn't work.
To run your scenario, copy it into the Blades of Exile Scenarios folder and start it using the Custom Scenario button on the game title screen.
Play from your scenario from start to finish, and, if possible, have friends play it too.
When testing your scenario, one useful feature is debug mode.
While playing the game, type 'D'.
This will put you in Debug Mode.
Monsters will no longer move or attack you, and you will be able to play much faster.
When you make a change in a town, before testing it, be sure to leave the town and type '>'.
This causes the game to forget everything you've done in that town.
If you don't do this, your corrections may not be remembered properly.
Finally, if you edit your scenario while playing in it, whenever you save a change go back to the game and reload your save file.
Otherwise, the game may not read the scenario data properly and crash.
