Professional Deeeepers: Please work on this. It is a rather important staple of the game and has very little in it.
Strategy and skills to use Edit
The King Crab is a Tier 2 animal. It has many different biomes it can go into, namely the Deeeep, Deeeep Arctic, and Arctic.
As a King Crab Edit
You deal 30% of the damage someone deals to you if they hit you. Despite how good this sounds, you're still pretty vulnerable. Use your speed and variety of biomes you can survive in to escape enemies. This ability does allow you to take on Tier 3 animals such as the Giant Isopod pretty easily head-on, however.
