- Requires Hordes of the Underdark.
- This feat stacks with skill focus.
- There is no epic skill focus in ride.
- Epic skill focus in animal empathy can only be taken when gaining a druid, ranger, or shifter level; in perform only when gaining a bard level; in use magic device only when gaining a bard, rogue, or shadowdancer level. This would match the class restrictions on those skills if "shadowdancer" was replaced by "assassin".
- Epic skill focus in use magic device cannot be selected as a rogue bonus feat, but otherwise bonus feat availability matches general feat availability.
