The Concentrator Barbarian is probably the party favorite in terms of Barbarian Builds. It is a defense oriented build that buffs allies and tanks.

Conc Barbs (referred to as CB from here on), are the safest choice in Hardcore for their entire class and are normally the best received in a party. This is one of the tankiest builds for the class but also one that has low DPS. This build is meant for multiplayer and not solo runs!

Concentrator Build Gameplay

The  is a great addition to any party but incredibly weak on his own. Most of the CB’s issues stem from how heavily tanky the build is to begin with. CB’s will build High defense to tank almost everything for his party.

Specializing in different Warcries, the CB will act as the hub or centerpiece of their party’s battle formation. This centralized position allows for the entire party to benefit from the amazing buffs he’s providing.

Just like any other Barb build, players normally keep a couple of points in Berserk to deal with any bosses or PI monsters.

Concentrator Build Skills

As expected, the CB will put 20 points in the Concentrate skill first. This skill is desirable because it cannot be interrupted while it simultaneously raises your defense. If only every skill had this kind of 2-for-1 philosophy!

Skills like Battle Orders and Bash should provide enough life and CC to keep your Barb relevant in a fight. Battle Orders is great for your party because it raises your HP/Mana maximums. Bash is extra CC, which is great for any tank.

For extra damage look no further than Weapon Mastery. This skill is in every Barb build, like Berserk, because of its utility. Speaking of Berserk, guess which skill is recommended for just a few points? Berserk. Again, this skill has excellent synergy for this build. Berserk allows your CB to down monsters with the dreaded PI. It can also shut down a Necro in PvP almost immediately. Did you know that at high levels Berserk applies passively?
This means that at higher levels, the skill no longer has to be the active one to work. This means your Concentrate attacks will have the same Magical Damage modifier as Berserk.

Nice!

Other buff skills should only get 1 point: Howl, Shout, Battle Cry/Command.
Prerequisite skills should also get the same 1-point treatment. Tanky skills like Iron Skin and Natural Resistances are in the same boat due to diminishing returns on investment.

Off-builds are normally customized depending on the amount of points in optional skills like Increased Speed, Stun, or Taunt. Extra CC and mobility are all dependent on your play style.

 

Concentrator Build Stats

Firstly, the Concentrator Build needs to have enough Strength to carry and use their endgame armor and items.

Secondly, dexterity is useful for block but dependent on the build variant. Normally, players invest in getting Max Block.

Thirdly, vitality gets every leftover point! This is important as it will keep your CB healthy.

Lastly, Energy is left at base, just like most other Barb builds.
