You know the following about the Balthrok:
Combining the qualities of a bear, mole, and human, a balthrok resembles a massive, hairless beast with overly long arms. Its wide, powerfully built hands end in thick, jagged claws that can tear through armor and tunnel through dirt. Driven to aggressive acts because of overpopulation, balthroks slowly infiltrate and assault towns and villages from below.
Balthroks burrow through the ground, lying in wait beneath the surface to ambush prey. They sometimes wield crude weapons, usually taken from their enemies. Balthroks hate all humanoid life, and sometimes groups of them gather to destroy a village or town. They burrow beneath walls and homes, coordinating their actions to cause several important structures within a town to collapse at the same time. In the confusion that follows, they erupt from the ground and attack the townsfolk.
Strong and tough, balthroks rarely flee from battle. They prefer to stand and die, seeing defeat as a stain that only blood can purge. Balthroks prefer to fight at a place and time of their choosing. If possible, they sow an area with hidden pits and other hazards that disrupt their enemies’ plans and give them the advantage of surprise. One of their favorite tactics is digging a hole and hiding in it beneath a loose cover of earth, then leaping out to fall upon an opponent’s flank or rear.[/sblock]
