THE WOODEN GARGOYLE
Wooden gargoyles are artificial creatures created by powerful magic-users to protect certain objects or locations. They are carved from hard wood (e.g., oak) to be resemble wooden versions of their stone cousins. They normally are immobile, but fly into action when whatever they are protecting is threatened in any way. Wooden gargoyles have been treated by a magical lacquer to reduce their vulnerability to fire.
In order to create a wooden gargoyle, a magic-user must be at least 9th level, spend 3000 gold coins for special materials, and work on the gargoyle for 4 uninterrupted weeks.
Wooden Gargoyle: HD 4; AC 5; Atk 2 claws (1d4), 1 bite (1d4+1); Move 9 (Fly 15); Save 13; CL/XP 6/400; Special: Fly.
[Note: this monster is inspired by the wooden gargoyles -- such as the one pictured above -- that can be found throughout the University College at the University of Toronto, the college that I attended as an undergraduate many years ago.]
