Special Conversion Thread: Lycanthropes and their ilk

[Cleon]

Total HD for the breath weapon probably works out better for the CR.

Agreed.

Total racial HD for SR seems ok. The magenta text for Saves seems good too.

I feel using total hit dice for the spell resistance will work out better for the CR as well, especially as we're using total HD for the special attacks.

That is:

Spell Resistance (Ex): As weredragons age, they become more resistant to spells and spell-like abilities. The spell resistance is the same as the base dragon advanced to the weredragon's total hit dice. For example, a juvenile red fire giant weredragon with 16 dragon hit dice and 15 giant hit dice will have spell resistance 26, the same as a 31 hit dice very old red dragon.

Oh, and I updated the Weredragon (True Drakanthrope) Working Draft.
