1. Basarios hides underground and disguises itself as a boulder/rock. Finding it is not hard especially when it sticks out or is unique on that area (the shape of it specifically.)if you run into it, it'll jump up and damage you. Because of this it's recommended to (if you don't have any bombs) throw a rock or a paintball from a distance. Also enemies jumping at it can wake it up, so kill enemies in the area. The best possible way too damage it while not losing life, just bomb it. 2. Once you have found it, strategy is simple: Use a dragon on the belly, so break off the shell. How to Kill.
