Does Gentle Repose modify the body in any way other than slowing its decay and resistant to being raised as undead? Specifically, would a corpse preserved by Gentle Repose smell like "food" to a predator? If the wolf started eating the corpse, would the corpse be more or less tasty than an unpreserved fresh corpse?
(Background: In a game I'm DMing, the PCs failed to prevent the murder of their informant, but chased down the murderer before he could get far and accidentally killed him (forgot to declare knockout rather than kill). I didn't let them have a do-over as both the players and the characters were out for blood. The informant died cursing the name of the murderer; the murderer is a disciple of Orcus, and there's negative energy in the area so there's a good chance that either or both of them will rise as undead (the PCs figured this out on their own). The cleric decided to peform Gentle Repose both to deal with the undead issue and to slow the decay, but they left the bodies behind, exposed in the woods (they were pressed for time, planning to come back later for Speak With Dead or Raise Dead). Would it be reasonable to have a pack of hungry wolves come by and drag off the bodies or eat them up?)
