For the life of me can someone tell me where to find info on whether or not devils need to rest (I know they don't need to sleep). Can they travel indefinitely without fatigue?. I have a player whose sorcerer wishes to send off his imp familiar hundreds of miles ahead of retreating giants, but I told him that his little imp does require rest. He claims that his familiar could travel 24 hours straight because he doesn't need sleep. I think that with a Con score devils still suffer from fatigue.
Also, while on the topic. Under the empathic link section of the SRD it states that a sorcerer can teleport to an area seen by his familiar just as if they'd seen it first hand. My understanding of this would assumenthat this ability is still restricted to the 1 mile range of empathic link. My player further thinks that he could teleport to any area the familiar has seen before even in his past.
