Unconfirmed
The following enhancements appear in the game data files but their implementation has not been confirmed yet:
 * Energy of the Zealot I and II (very doubtful since the Paladin's SP enhancements are called Energy of the Templar, note however that the latter do not appear in the game data files)
 * Extra Lay I and II
 * Extra Smite Evil II, III and IV
 * Extra Turning I and II
