Changing a Special Unit's sprite between chapters.

[Vanya]

If I wanted to make a special unit get a new sprite set could I do it strictly with ENTD editing or would it require an event edit?

Well it is just like Ramza, and it requires some minor Event editing. I'm almost positive.

Right. ENTD only would create a duplicate if the unit has already joined.
What about guest units though? Could I load/save formation on a guest unit and change the sprite set, or would it be over written?

Edit: On a similar note, I can eliminate the sprite & job changes for Ramza with event editing, right? That would free up 2 sprites and 2 specials.
