are devil-touched feats supernatural in nature?

[dehro]

if I have the extend supernatural ability (http://dndtools.eu/feats/tome-of-magic--89/extend-supernatural-ability--1007/) feat, can I use it to double the duration of the regeneration I get from devil's stamina (http://dndtools.eu/feats/fiendish-codex-ii-tyrants-of-the-nine-hells--67/devils-stamina--602/)?
I'm guessing they are, but can't find the ruling.

hmm Devil's Tongue says it's a mind-affecting, language-dependent, supernatural
ability.

Doesn't say so in Stamina. But I would rule yes it's a supernatural ability since the other feat is.

[Venger]

no. feats are extraordinary unless otherwise specified (such as exalted feats) while the daze effect of devil's tongue is supernatural, the feat itself is not. so if you're in an AMF, you can't use the ability the feat grants, but you would still derive the armor bonus it gave if you possessed devil's flesh, for example.

[dehro]

so, no regeneration.. then I'm screwed because binder allows me to pick a bonus feat, but only from the shortlist that includes extend supernatural feat.. not the other version.
meh...

No, feats are untyped unless explicitly typed. There is no default typing. (The passing remark about them being extraordinary in Book of Exalted Deeds disagrees with the Player's Handbook, and the PH is correct due to being the primary rules source.)

ah, of course. but the point still stands that they are not supernatural
