Tips and tactics
/cancelaura Bladestorm
 * Warriors in Bladestorm can only be stopped if killed.
 * When snared or rooted, Bladestorm can be used to stay on your opponent, as well as dealing respectable single-target damage. It can also be used as a defence against incoming crowd control effects such as Polymorph.
 * You cannot use any other abilities during Bladestorm. This can make it very easy for some classes to escape you, without fear of Charge, and prevents you from interrupting using abilities such as Pummel. If needing to interrupt healers or chase ranged types, consider not using Bladestorm. You can also cancel Bladestorm prematurely by right-clicking the buff, or by using the following macro:
 * Bladestorm does stack with warrior buffs and abilities such as Recklessness. This ability must be triggered before using Bladestorm.
 * Since warriors in Bladestorm usually deal a lot of damage, and cannot use any other abilities, Bladestorm often generates a large amount of rage. Choosing to Bladestorm when you are already low on rage is ideal, preventing your DPS from dropping and getting maximum benefit from the ability. Burning spare rage with abilities such as Heroic Strike before Bladestorming can allow you to minimise rage wastage.
 * Bladestorm can be used while charging, jumping or falling. Since Bladestorm's first whirlwind is performed instantly, be sure not to waste any of its duration while still out of range of your targets.
 * Warriors still deal normal auto-attacks while Bladestorming.
 * Fury warriors attack with both weapons during Bladestorm.

Defence against Bladestorm
Bladestorm has a number of weaknesses:
 * The warrior is unable to use any other abilities during Bladestorm, such as Charge or Pummel. Abilities such as Blink and Disengage can make Bladestorm worthless if timed correctly.
 * Bladestorm's damage output is most effective against groups of enemies. When in groups, prevent this by running in different directions. The warrior will have to choose a single target to chase, at most dealing a fraction of the ability's potential damage and largely wasting the cooldown.

Trivia

 * The unusual description of the old version ("you do not feel pity or remorse or fear and you cannot be stopped unless killed") is a reference to the 1984 film The Terminator.
 * Bladestorm is the ultimate ability available to the Grom and blademaster hero units in Warcraft III: Reign of Chaos and Samuro in Warcraft III: The Frozen Throne.
 * Bladestorm is one of Samuro's Heroic Abilities in Heroes of the Storm.
