It's easy to you because you can search a npc and edit its stats then update info or insert with another id.
It is also supporting multi languages (users can add more languages from languages.txt)
Tested on Gracia CT 2.2 & CT2.3 (don't know if on the other chronicles npc table was different or not).
(I know there is another npc editor around here but this one is more user friendly

Application fixed! Sorry for the last share..
V 1.0:
NPC Editor.rar
NPC Editor.zip
PS: you need to have .NET Framework 2.0 installed
