  • The Assault Aura is a great tool for pushing enemy towers, as it provides reliable attack speed and armor. In addition to that, it also reduces the nearby structure and enemies' armor which can help the nearby ally heroes take them down.
  • The Attack Speed aura works on illusions, but the armor aura does not.
    • The aura is also good for controlled units especially with low base attack time like Necronomicons and for the bonus armor and armor reduction of the enemy.
