Giants are huge. Really huge. The survival of the giant is not due to his intellectual might; most giants are cursed with extremely low intelligence. The giant that thrives is the giant that depends on brawn instead of brain. A giant's sheer size prevents the use of humanoid armor, but also grants him the use of large weapons which he can wield with deadly force.
Extremely large size: the giant is unable to wear standard armor.
Command: bash <door>
The sheer might of a giant allows him to bash open a door, resulting in both a broken door and a new opening.
By slamming his powerful fists into the ground, a giant can cause an entire area to tremble with the force of a small earthquake. Anyone in the area will either be flung in a random direction or crushed beneath the giant's titanic fists and take damage (10-50).
