'with the selected natural attack' should just say 'with gore'.
Other than that, looks alright, but favored classes should come with a selectable bonus each.

Suggestion fixed. But I don't know what to do with the Favored Class bonuses, never learned out how to figure them out.

[David]

The easiest way, copy existing bonuses.
