Here is the same module but with a NPC that can delevel characters with options for - 1000 5000 10000 and 50000 xp. He is just behind the tavern in the rural district of etum. I hope vampires / liches and drow can also use him (pure humans can).
I noticed a conversation already present for xp and lvl loss (fixes in choices) in the module, but I don't know the location of that NPC (if the conversation is even used). May be we don't need mine and can use an available one, but I don't know its location.
It worked by creating a conversation with scripts, attached to the choices in it, but I can't reuse the same conversation file for other NPCs - only with the one I originally created it for. Do you know how to attach prepared conversations, for any NPC ?
P.S. If I can't attach the file (4.44MB size) and can't use external links, how can I give you the file ?
