Frenzy Barbarians also fit the classic Barbarian vibe with dual-wield weapons and lots of hacking and slashing. Frenzy Barbarians go far and are almost always a crucial element to a team in the late game. Only Barbarian can complete the set but it is not uncommon for other classes to wear a combo of belt + gloves + boots for example as their bonuses are quite good. This is another popular build for the Barbarian due to its versatility of use.

It has mostly Exceptional items with 2x Elite items being the weapon - The Ogre Maul and the Armor - the Sacred Armor. Immortal King is a full-fledged Barbarian set which includes 6 pieces (everything except jewels like Amulet and rings) including a weapon.
