Berserk Effect: A powerful attack that leaves the Barbarian more vulnerable.

• Berserk completely converts damage to magic damage so you cannot steal life/mana with Berserk, even with life tap.
• You don't take damage from Iron Maiden and Thorns if you just go "Berserk". Because they only reflect physical damage, not magical.
• For the stated duration afterwards your defense is zero. You also do not receive the Iron Skin or Dexterity bonus. You can still block as if you are using a shield, however. A defense of 0 will let you block all the time, thus quite often hinder you from doing anything else. Consider not wearing a shield.
