Saves of several outsiders a little off?

[Wasum]

Hello everybody!

I am a little confused by the saves of some demons I checked. While I can rebuild the saves e.g. of a Succubus easily I am kind of struggeling with some of the higher CR demons.

For example the Balor has a +17 ref save at 20 HD and 25 dex. I have no idea how to get there.
Same with the Nalfeshnee with +21 will save at 14 HD and 22 wis.

Could you let me know what I am missing? There are actually more examples where I have no idea how to get the written saves so I feel like there is something I don't understand.

Nalfeshnee:

Base Will Save: +9
Wisdom bonus: +6
Iron Will feat: +2
Unholy aura: +4 resistance bonus

For the balor, hmmm....:
Base Reflex save: +12
Dexterity bonus: +7
Unholy aura: +4

Not sure here.

With outsiders, you get to choose which two saves are good saves, and it looks like the balor gets Fort and Will. So, it would be:

Base Reflex Save: +6
Dex bonus: +7
Unholy aura: +4

Forgot that point. Good catch.
