Looking for a specific feat

[Talbot]

I may have imagined its existence, but isn't there a feat that makes you immune to the fatigued or exhausted condition? Or weakens them? Or something?

[Zaq]

Maybe something warforged-related?

Edit: Derp. Warforged are already immune to that. I dunno offhand.

[Thurbane]

Tireless (PGtF), reduces exhausted/fatigued by one step.
