So pretty self-explanatory, I want DD to be discoverable earlier, say after the Finath River plot battle. I had assumed this was a matter of editing the World Map Editor/Conditions spreadsheet, but even after reading the World Map instructions wiki entry, I can't make sense of the DD info enough to do it. Is there a post that explains how the DD triggering works, or is that in another area altogether?
You should be able to make this happen by making some edits in an event. A bar scene needs to happen in Warjilis Trade City and this is triggered when variable A4=1. Go to the event you want DD to open up after and simply use "add variable" to open this scene. If you want you could also change the map color by "zeroing" out the variable for the color of Warjilis (273). This would be a reasonable alert that something is happing there.
Then it's just a matter of running the bar scene and that one will draw the map and location for DD.
