Petardo

Although Petards do deal blast damage as their primary means of attack suggests (that is, they explode), they do so in a very small area - the same area that a Cataphract with Logistica or War Elephant does. Ranged units are a danger to them, as they can easily kill Petards without receiving damage. A good use for Petards is neutralizing key enemy buildings or siege units near the player's Castles in the Castle Age. They are also an excellent choice for quickly breaching walls, taking only two to destroy a piece of Stone Wall. However, they are not cost-effective against buildings, especially when compared to other siege units. They are sometimes used in the Sudden Death game mode to quickly take out the starting Town Center, or Regicide to destroy the garrison location of the King to expose him to units that can kill him. When used (especially against Castles), it is important to line them in staggered formation. That way, they take less damage from the volleys of arrows since every volley only damages one Petard.
