Concentrate is a Barbarian Skill in Diablo II.


Sometimes a series of blows is not nearly as effective as a single, concentrated strike. A Barbarian trained in this skill learns how to focus his strength into a single blow that cuts through the guard of an enemy and slices through their armor. This technique also puts the warrior in a superior defensive position.

General InformationEdit


  • Gives synergy to:
Bash: +5% Attack Rating per level
Stun: +5% Attack Rating per level
  • Receives synergy from:
Bash: +5% Damage per level
Battle Orders: +10% Damage per level
Berserk: +1% Magic damage per level

The main benefit of this attack is that its swing is uninterrupted, even in a crowd or against a faster foe. This is an efficient skill at a cost of 2 Mana, especially with a strong weapon with high damage, or one with at least a small bonus to Mana Leech.

As Concentrate has Battle Orders as a synergy, it is an attractive skill because players do not have to spend extra points for the sole benefit of increasing life/mana. Berserk's additional magic damage is also helpful against Physical immune monsters after about ten points due to the amount of magic damage done without having to switch to Berserk (which has the disadvantage of reducing the user's defense). The defense bonus is also helpful because it still provides a significant defense bonus even if a shield is not equipped.
