Tiamat's Rebuke is certainly a shield intended for use by a physical fighter. With added Cold, Fire, and Lightning damage, Tiamat's Rebuke could be said to bestow a fighter with Spectral Hit. When combined with a weapon such as Baranar's Star, a fighter could have powerful elemental hits effective as far as Hell Difficulty.
However, Tiamat's Rebuke has good defenses as well: it boosts all of a user's resistances by a moderate amount. A character could choose to add a socket with the appropriate Act V quest, then insert a perfect Diamond, in order to further increase its resistances.
The chance of casting Hydra, Nova, or Frost Nova, although promising, is not incredibly effective. For one thing, the chances are low. For another, even if they are cast, the levels on all of them are too low to do any significant damage. The most useful would be Frost Nova, which would chill any surrounding enemies and allowing for escape or easy retaliation.

- Considering the name, item type, and the variety of bonuses it offers, Tiamat's Rebuke appears to be named after the mythological dragon goddess, Tiamat.
