Like all giants, stone giants have a size advantage over most adventurers, and are resistant to physical attacks. They also share with other giants an innate mastery in bash, body slam, and enhanced damage, although their slow minds make them vulnerable to mental attacks and spells. Having no additonal resistances they also lack any true weaknesses. They are neutral in alignment.
Stone Giants, unlike the others possess the ability to use boulders as thrown weapons in certain types of terrain.
