Q268: Where can I find the latest polymorph errata? When I try to google it the links on the Wizards webpage brings me to the errata for books, and I can't find a Polymorph errata in any of them.
A268 The rules compendium has the polymorph subschool's most current rules on page 122. They seem identical to those found in Player's Handbook II. I have not found the augmented subtype part yet besides this in the SRD:
This seems to just grant the augmented type, not race like dwarf or elf. Humans might be in luck at least since there is a human subtype (not refering to the humanoid subtype). Working on a trick, might be out of luck.
Also I did not see anything in the FAQ.
The Polymorph subschool stuff doesn't affect the original Alter Self, Polymorph, and other spells based on them at all. This is stated in the sidebar called "Spells that came before" in the section of the Polymorph subschool writeup. Basically, WotC thought the original Polymorph line of spells was too overpowered to even bother fixing. So they made up different spells, and suggested that you use those instead of the originals.
To figure out how Alter Self, Polymorph, and the other original spells were supposed to work, you have to dig back into the Errata
before the Polymorph subschool stuff. Basically, you don't gain/lose hit points despite changes to Con, and everything else is pretty much as written in the spell descriptions in the SRD.
