Guardgoyle

Guardgoyles are constructs created by Zhentarim wizards to protect their treasures.

They resemble baby gargoyles, hence their moniker, and their small stature (2 feet tall/long) allows them to hide in the wizard's posessions, ready to fly out and strike if it senses a presence in the room it is guarding that isn't it's creator or one of the 5 people it can be programmed to not attack.

If not destroyed, the magic animating them will last as long as their creator lives. Any repairs that they need can be administered with a single stone shape spell. Due to these facts and that they only cost around 1000 gold pieces worth of raw materials to create, guardgoyles are cheap and effective guardians.

Greater guardgoyles tend to be between 4-6 feet tall and lack the ability to fly, they are also much more expensive to create and require much more powerful magic to animate them.
