Hope I can use this thread to post another question about dual-classing.
Is it ever possible to dual class into a prestige class?
For example, if I would start off as a basic Fighter, will it be possible to dual class into a prestige thief, such as Swashbuckler?
I have suspicion that one has to start off with the prestige class, and then dual into a generic class, if even that works at all...
If anyone knows firm answer, this would be much apprecaited!
No, it is not possible without mods. As you say, you must choose your 'kit' at primary class creation. In the original BG1 you could choose a mage kit if you dual classed xxx/mage, but not in BG2. Even if you import a Thief/Conjurer into BG2, your conjurer status will be lost, and you will be offered a choice of thief class at import.
