Perhaps I'm missing the obvious here, but I want to create a new merchant. I cannot seem to change the services offered by the NPC. I'm having a rough time even trying to figure out how that is determined. Paging through and trying to pickup what I could find about it in Morrowind Mod Maker Manual and Morrowind Scripting for Dummies hasn't quite helped me yet. I tried checking some of the posts made in the past year but none of the titles stuck out as specific on this topic as I was looking for. The answer just seems to escape me wherever I look and I'm getting pretty sure that it's much simpler than I think

Steps thus far:
I copied an entire house from another location. Then I moved some stuff around and changed some names to reflect the new occupant. There's a chest behind the merchant containing -1 items of what is going to be sold. If my memory serves me right, that'll give a limitless supply.

So all I really need now is to make the particular set of items and services available (I'm making an enchanter btw, I want to add a training option).

Also, my ideal situation is to tie this in with the stronghold quests, making it appear after level 3 when other residents show up. I haven't bothered to try and tackle that yet because I'm not sure when I'll be starting a new game to make use out of that kind of feature. It would be somewhat handy as I'm thinking of adding some content dependent on a stronghold and reputation.

Thank you for your time

I'm assuming you created a new NPC for your mod?

Set the NPC class to 'Enchanter Service', then click on the 'AI' button and the 'Services' tab. By ticking the various boxes you can decide which items your NPC buys and sells, and which services the NPC offers. Make sure to set 'barter gold' to whatever amount you think the NPC should have available. Check the 'training' and 'enchanting' tickboxes.

If you can't change any of the tick boxes, try unchecking the 'auto calculate stats' box.

If you want to have the shop appear once the stronghold has been built you need to make sure your exterior objects have unique IDs so that they can be disabled until required. Then just enable them via script.

The "auto calculate stats" box is what was holding me back, I didn't even think about it limiting what the NPC could do. Thanks alot, knew it had to be one little thing that I was missing I checked out the script for the other homes in the area and it should be cake to add the extra bit.
