Attach (Ex): A dire weasel that hits with its bite attack latches onto the opponent's body with its powerful jaws. An attached dire weasel loses its Dex bonus to AC and thus has an AC of 12.

Blood Drain (Ex): A dire weasel drains blood for 2d4 points of temporary Constitution damage each round it remains attached.

Dire weasels stalk their prey in the dark and then leap on it, biting and clawing.
