I didn't make it!
How would I go about getting Atris as a party member? I've seen mods with Kreia's dialogue only have Atris skin. What I want is a completely new character in Atris. I'd even settle for Atris over Kreia and rewritting the dialogue myself. How would I go about this?
I haven't really done this before, but it can't be all that hard can it?
First off, you'll have to edit Atris' uti to your liking (I'd make her a level 10 sentinel).
Second, you'll have to make a script which makes her become a member of your party, and at the same time, remove Kreia.
Of course, you'll have to make portraits representing her dark-side transitions.. (There is actually a portrait of Atris in-game... cut content)
That's basically what'll get the mod going... though who knows what side-effects there might be not having kreia around. To make it work right, you may need to reassign many dialogs to Atris instead... or create new ones and find yourself a good voice actor.
