Crypt rat

The Crypt rat can be found under the Barrows tunnels and in the Chaos Tunnels. Despite their combat level, they are weaker than they appear unless they come in large amounts. Due to the disgusting appearance of the crypt rat, not even a cat will try to catch it.

They don't pose a large threat to most players, but with many of them together along with other monsters, they become an annoyance. Unlike most rats, they ARE aggressive, and can usually land hits, unlike regular rats.

They can be handy as they can used to heal if the player completing the barrows minigame has guthan's armour.
