I created a Spellmaker for my Stronghold mod and I wanted her to say that she was skilled in all Colleges of magick and could sell and create spells from all schools.

So I copied a character who was originally skilled in Destruction and Alteration and changed it as I wanted, and edited her dialogue for My Trade.

But this seemed to change the dialogue for ALL Mage Service characters who were skilled in Destruction and Alteration.

So I reverted to an earlier esp from before I changed the dialogue for My Trade, but now ALL the Mage Service characters at the Balmora's Mages' Guild say they are skilled in Destruction and Alteration, even though they sell spells from their original schools like Illusion and Conjuration.

How do I fix this?

How do I use new dialogue options for an NPC to say different things under the standard headings without changing them for the entire game?

Cheers!

You should create a copy of (right click/copy) the original dialog line, select the copy (the one highlight BEFORE the original... if in doubt, enlarge the hidden InfoID column between the Info and Disp/Index columns and verify the id is not of the original line) and add the ID filter combo box for your NPC id
