Onyx dog figurine

This figurine appears to be a miniature statuette of a dog, approximately 1″ long, carved out of a chunk of onyx. When the figurine is tossed down and the correct command word spoken, it transforms into a large, black dog, with the statistics of a riding dog except that it is endowed with an Intelligence of 8, can understand and speak Common, and has exceptional olfactory and visual abilities (it has the scent ability and adds +4 to its Perception checks). The dog has 60-foot darkvision, and it can see invisibility.

If the figurine is broken or destroyed in its statuette form, it is forever ruined. All magic is lost, its power departed. If slain in animal form, the figurine simply reverts to a statuette that can be used again at a later time.

An onyx dog can be used once per week for up to 6 hours. It obeys only its owner.
