Crocodiles are pretty badass. Even out of water they can move fast. The ancient Romans feared them. Fantasy crocodiles are even worse. They're smarter, bigger, and meaner, and some have magic resistance. Although some crocodiles have the gift of speech, they rarely use for any other purpose than taunting their prey or luring it into a trap. In at least one account, crocodiles have been known to shadow an adventuring party, trying to provoke them into an ill-advised attack. Some crocodiles also live in symbiosis with will-o-wisps, who lead prey into deep mires where crocodiles can ambush them at their leisure.
