Didn't realise that mudcrabs were that big

Terrible creatures, mudcrabs.
"I saw a mudcrab the other day. Disgusting creatures!"
In all seriousness, mudcrabs are no joke. My last character dabbled heavily in illusion, so I spent a of time running around and frenzying things. Mud crabs can easily defeat frenzied wolves (up to three at a time!) as well as misc deer and elk. Sabercats usually take more than a hit to kill them, which is pretty good considering sabercats can two shot ME at lower levels.
