Tyrosaur (also known as the Earthquake Creator) is a powerful boss in Precasia.


Tyrosaur can be spawned by holding the use button down while holding a Bone Horn, charging it up like a bow. Tyrosaur will spawn nearby after a while. It will despawn if the player gets too far away from him, or if the difficulty is set to Peaceful.


Tyrosaur will pursue players that come within 16 blocks of him and attack with melee.

Every 5 seconds a rumbling sound will be heard and Tyrosaur will stomp the ground, dealing 10 (♥×5) points of damage to all players currently standing on a block within 35 blocks on any axis. This damage does not ignore armor.

While above 3.5 seconds until Tyrosaur's next stomp, it has a 1 in 150 chance per world tick to lunge towards the position of its current target.
