Gronk

Gronk is a mace used by the Crocodile Tribe. They are made by Cranvil.

Official Description
The croc tribe blacksmith, Cranvil, is a mace master. To him, a mace is not just a mace, and although they look alike, each one he forges has to be unique. So he names them after the noises they make when they hit something hard. Krank and Gronk are examples of his fine craftmanship. The names are also his way of getting around spelling long words.
