I've been tinkering with the mod editor a bit to see what is possible, and in the process I came up with a number of questions about modding for this game. Most of these questions are about the in-game mod editor, though a few may go into more complicated aspects of modding:

• Can "normal" items be given a use in the mod editor, such as an item starting a plot (like the base game books do)?
  
• Is it possible to add items to store inventories from the mod editor, or does it require things like compiled scripts and use of the API?
  
• In the tooltip for dungeon level offsets, it sounds like negative offsets are possible, but the values clamp to 0. Are negative values for the offsets not possible in the editor? Does it require a specific encoding for the negative sign? (Such as a two-byte version, which didn't work for me.)
  
• Is there a way (using only the mod editor) to use artifact spirit portraits for plot dialogues? They seem to be used this way in some base game plots, but I can't see how it works in the editor.
  
• Is there a command that can be used to make time pass after a plot step?
  
• Where can the default times for certain actions (such as cultivation or geomancy) be edited? I've seen mods that tweak these values, but it's unclear to me how they work.
  
• This is more of a question only developers can say anything about at the moment, but is there any indication that the "eccentrics" (unique NPCs) system in the upcoming patch will allow for the mod editor's use in creating new characters under that system?
