Dragon crabs tend to be greedy, both in carnivorous appetite and for treasure. Like some dragons, they often amass vast piles of gems, coins, and any other wealth that can survive at the bottom of the sea. Some also collect shipwrecks to decorate their lairs. Dragon crabs enjoy the pain of living creatures, especially intelligent ones, and often make a hobby of devising clever means to lure humanoids to their lairs to make them suffer for entertainment. Most dragon crabs harbor a strong dislike of wizards.
