Also, the Frenzy Barbarian has access to several useful abilities which can help him out of any situation which he might find himself in. This way the player can freely deal damage with Frenzy and increase his attack speed without having to worry about controlling his character. To combat this downside, the player has to use the Frenzy skill wisely, mostly when all the enemies in the given room are already close by and stunned. With the Frenzy Barbarian avoiding such situations can be very difficult. No matter what you should never get yourself into a corner or surrounded.

One of the most important things when playing a melee character is having control over one's positioning. Though the increased movement speed makes it easy to traverse large distances it becomes just as easy to run into dangerous situations or run right past the enemies the Barbarian was trying to attack. Should the movement speed increase to the skill's maximum potential, controlling the movement path of the Barbarian becomes almost impossible. Even with movement speed increased by only a few percent the Barbarian becomes very difficult to control accurately. While increasing one's attack speed is a powerful ability to have with a melee character, increasing one's movement in the process can be a curse. Each successful attack with Frenzy greatly increases the character's attack and movement speed up to a certain threshold. Though Frenzy is an extremely powerful attack, it should not be overused.

The main concept which the player must understand when playing the Frenzy Barbarian is control. If need be the character can also utilize many of the skills he aquires while trying to unlock his core abilities, thus becoming extremely versatile and able to deal with any situation. To avoid being outnumbered and overrun, the Frenzy Barbarian also uses the powerful War Cry to stun all nearby monsters for several seconds, effectively allowing him to take as long as he needs to kill his enemies. The Frenzy Barbarian combines the quickness of the Frenzy and Double Swing skills with the sheer power of dual wielded weapons to quickly distribute large amounts of damage among several foes.
