Rocnars are large level 100 beasts that are put in oubliettes to "execute" players. The rocnar looks like a big one-eyed green ork with two long fingers on each hand. Although they require a higher Construction level to install than flame pits, a flame pit is more popular. This is due to the fact rocnars aren't very accurate in their attacks and can be prayed against, and they can be killed quickly by multiple players in the cage. As a saw is not required to 'build' a Rocnar, the bonus from the Crystal saw will not work.
