Werehouse?

Dungeons and Dragons Shenanigans

After an encounter with a Were-Rat, the party investigated a warehouse to find out more (a story for another day).

 This prompted the suggestion for a werehouse...

 Werehouse (rare creature):

A human with the ability (curse?) to turn into a large storage facility at the full-moon. When transformed into the werehouse form, the creature has 5,000 hit points and AC20.

It is unable to cast spells, talk or use objects in this form. If reduced to 0 hit points, the werehouse reverts back into it's human form.

More powerful werehouses have the ability to switch forms at will, providing storage space for others of the tribe. Werehouses are often found in large cities, especially those with large amounds of trade, where they are less likely to be noticed during the full moon.

It is not known how many werehouses there are in Waterdeep, but watchmen are advised to report any large building they see that they believe was not there the day before.
