Sure, but only to alternative innate class abilities, and not using the PHB2's "Retrain a Feat" option, which is what the OP asked about.Donovan Morningfire said:Actually, there are options in a few books, PHB2 and EtCR that immediately come to mind, where characters can "re-train" what are viewed as innate class abilities.
Paladins can drop the mount to gain a charging smite, Rogues can drop Uncanny Dodge at 4th level to get an ability to inflict a hefty AC penalty to a flanked foe, Clerics can drop Domain abiltiies and Turn Undead for some pretty powerful tricks (such as EtCR Destroy Undead, which the dwarf cleric proved last session can be utterly devastating to undead with low hit points). So the precident is there to retrain innate class abilities.
That option may only be used to retrain feats received as feats, and only to other feats for which the character would have qualified when taking the original feat, and even then only if the feat you're losing isn't acting as a prerequisite for something else you have.
So for instance, even if you consider a 1st-level fighter's Shield Proficiency clqss feature to be a feat, you can't retrain it using the "Retrain a Feat" option, because a 1st-level fighter would not have had the option to swap it for another feat in the first place. If it wasn't an option then, it doesn't suddenly become an option later, even with Retraining rules.
