I'm confused by the paragraph on playing superntaural creatures in the Optional Rules section.

If I use the creature builder rules to make up my own playable race... how does that work? Do I total their DP, divide by 100 and make that their level mod?

I've been trying to retro-engineer the Hell races to see if this works out. I've only completed the Jayan, and they are over 100 points but far less than 200 (I think they came out around 120 or 140). Is that why they are worth only a single level adjustment?

Can anyone help? It would be really great to be able to use it for crafting my own setting races.

did you take into account the -10 penalty to MR, not being able to take the unnatural size advantage and immortal soul penalty to XP? this should reduce to about 100
