The DM team is reversing a long standing rule about the Shifter class. The Shifter class is now a permitted PrC. Players must submit an application to the DM team to be approved for this class, just as players do currently for the Blackguard PrC.
The shapes of the Shifter class have been modified to make this possible and keep things balanced. Some shapes have replaced old ones and others remain the same shape but may have been tweaked. Note that the radial menu has not changed. Anyone playing this class will have to learn how the old name maps to the new shape. Below is a list of shapes for the Shifter class. I think it is fair to say some shapes were chosen for RP purposes instead of combat purposes.
Greater Wildshape I
Greater Wildshape II
Greater Wildshape III
Greater Wildshape IV
Undead - is now Giant
The DM team reserves the right to adjust any of these shapes as we see fit, or even replace an existing shape with another.
