Crogs have a rocklike hide with a broad row of sharp spikes on their back. They have a huge mouth filled with very shrap teeth; this jaw is the Crog's primary weapon. Crogs are very aggressive and attack almost everything except the very largest of creatures.
The most common place to find this creature is on the island of Cairn, but they can be found in other wastelands as well.
Crogs can be used to train archery and magic quite easily, if you have a crog near your city it's recommended to use it to level.
