I would like to create a shapeshifting character.
I'm used to Neverwinter Nights' Shifter prestige class, I would like to play something similar in DnD 3.5.
I would appreciate some pointers about similar combination of class and prestige class to achieve the same result, also please tell me in which manual I could find it, so I can look up more about it. I'm not really interested in a powerful build, just some advice on what to look for to create a character that could shapeshift a lot, based on the situation.
Thanks in advance.
