The Disputable Dog

A wooden statuette of a mastiff with beautiful detail that's small enough to fit into your pocket. If you use an action to speak the command words ("Quite Disputable!") and throw the figurine to a point on the ground within 60 feet of you, the figurine becomes a living creature.

The creature is friendly to you and your companions. It understands your languages and obeys your spoken commands. If you issue no commands, the creature defends itself but takes no other actions.

The creature persists for up to 6 hours. At the end of the duration, the creature reverts to its figurine form. It reverts to a figurine early if it drops to 0 hit points or if you use an action to speak the command word again while touching it. When the creature becomes a figurine again, its property can't be used again until the next dawn.

The Disputable Dog (TDD) has an Intelligence of 8 and can speak Common. He also has darkvision out to a range of 60 feet and can smell or sense invisible creatures and objects within that range. He has advantage on Wisdom (perception) checks that rely on hearing and smell.

Personality. The Disputable Dog's original purpose is long forgotten. He could have been made to function as a guardian or a companion to a lonely student long ago. TDD is haughty and highly disapproving of anything dangerous. He is, however fiercely loyal and protective when faced with danger - as long as that danger does not include fire.

Being a creature bound to a wooden figurine, TDD has an irrational fear of fire and will take great precaution when around it. When faced with either magical or non-magical fire within 30 feet, TDD must succeed a DC 11 Charisma saving throw or become afraid until the end of his next turn and must take its reaction to move up to its speed away from the source. He must repeat this saving throw each turn. Once a saving throw is succeeded in this manner, TDD is immune to this effect until reverting to his figurine form.
