This ring enables its wearer to exercise complete control over mammals with intelligence of 4 or less (animal or semi-intelligent mammals).

Up to 30 HD of mammals can be controlled.
Control extends to such limits as to enable the wearer to have the creatures controlled actually kill themselves, but complete concentration is required.

<Effect.Exception>: (Note: the ring does not affect bird-mammal combinations, humans, semi-humans, and monsters such os lammasu, shedu, maniacores, etc.)
If you are in doubt about any monster, it is NOT a mammal.
Obviously, rats, weasels, herd animals, dolphins, and even unicorns are mammals, but intelligence will preclude control of the better ones.
