Stoneform

Stoneform (also known as or similar to stone flesh, stoneskin or avatar) is a dwarven racial ability that has many effects without a downside. It reduces damage taken, so handy for melee attacking and tanking. It also rids you of all poisons, diseases, and bleeding.

The Titans crafted the dwarves from stone to assist them in creating the Azeroth of today. Since this discovery, the Ironforge dwarves zealously search for any sign of their ancestors or the Titans. This newfound knowledge also unlocked enchanted energies of their heritage, enabling Ironforge dwarves to perform spectacular feats. The dwarves have rediscovered the power to return to their original forms, and turning skin to stone. They firmly believe that other powers are waiting to awaken within them; all they need is the key.

Tips and tactics

 * Stoneform is incredible against rogues, and effective for any class. With this skill, even warrior, hunter or rogue dwarves can dispel some of their debuffs, so it's a plus for soloing, especially when you are inflicted by Diseases that tend to last for 5 to 30 minutes.
 * Since it removes bleeding efects it is very useful during some raid encounters where you take heavy bleeding damage and you would otherwise die. Example: Moroes in Karazhan.
