Gargoyle

The gargoyle is a grotesque winged monstrous humanoid with a horn on its head and stony hide.

Encounters
The gargoyle is a monster, found on all levels of the dungeon.

If you listen before entering a room with a gargoyle in it, you will hear "flapping wings."

It has an AC of 13. It has a strength of 14, or +2 to hit you. Its dexterity is also 14, but it only has +1 to avoid spells.

It does 3-18 damage on a hit, and almost always has HP of 30 or higher. The most common amount of XP is 35 for beating a gargoyle.

Strategy
You should try to have a Longsword or better before attempting to kill a gargoyle. Spells might help, but it has a decent ability to dodge them. Scale mail armor or better is highly recommended.

It will be a good idea to just escape if you are not ready to fight yet.
