User Commentary
Stone Skin is often compared to Shield, which has similar effects. They both reduce the amount of damage creature stacks receive. The main difference between these two spells is that Stone Skin also works against ranged creatures while Shield only reduces hand-to-hand damage. A rule of thumb whether to use Shield or Stone Skin in hand-to-hand combat is that if an enemy's attack skill is greater than your defense skill, use Stone Skin. Of course, with both spells active, your troops will receive considerably less damage.
Advanced/Expert Stone Skin is only strictly better than equal-skill Shield if the difference between your unit's defense and the opponent's attack is exactly 21 or 22. That means Shield is almost always preferable, unless you expect ranged attacks.
