The length of a long weapon's shaft was effective for keeping enemies at a distance, and made it very difficult for them to evade. Long weapons could only be countered by a heavy weapon, another long weapon, or the Hidden Blade.
Should he manage to disarm a long weapon from a guard, Ezio Auditore da Firenze would often discard it once combat was over, or upon sprinting away. This was likely since, whether the weapon was intact or broken, it would be too difficult to carry while moving freely across streets and rooftops.
The Sweep attack was a special technique performed with a long weapon. Any Seeker could perform this technique, and Ezio in turn learned it from the fight instructor at Monteriggioni.
Though it could be interrupted, the sweep could be executed with either a short or long preparation time; the more force placed behind a sweep, the wider the arc it would affect. The maneuver was, however, impossible to perform without standing still in an open fight.
Upon being executed, those caught in the sweep would trip and fall to the ground, while those behind were knocked over by a blow to the head. However, sweeping more than three times with the same long weapon would cause it to break.
After the siege of Monteriggioni, Ezio's proficiency with a long weapon improved. His sweep attack would no longer trip guards, but would instead slit the throats of all enemies within range.
Additionally, Ezio learned a second special technique, which allowed him to throw a long weapon into an enemy from a distance.
Though it would generally break through the guard of any other weapon, the heavy weapon's smash attack could be blocked with a long weapon. The defender would avoid all damage, but the parrying weapon would shatter into two.
When a long weapon was broken, the owner could still continue to wield the remaining half as either a bladed or blunt medium weapon; depending on whether the top or bottom segment was used.
Alternatively, Ezio could counter as soon as the weapon broke, upon which he would stab both pieces into the attacker.
