They all seem pretty weak to me, and don't give anything herods don't already have. Clearing herod's dungeon is kinda pointless for a character who can band to herodias, since she clears it anyway. Herodias is just overall weak, and herod's dungeon already pretty much acomplishes what she would do. Herod Agrippa I's ability is too narrow in scope, and herod's banquet would never be used (with Rash Oath, Beheaded, Salome all accomplishing the same effect), unless it was territory class, and probably not even then, because it really isn't that powerful.
