The game also enables the player and computer-controlled commanders to use "charms" before entering battle. These affect the tide of battle by damaging your opponent's forces, healing your allies or flooding parts of the battlefield, forcing your opponent to change his tactics. These charms make the downtime between battles more entertaining and force you to move your army intelligently to avoid getting slaughtered. Upping the difficulty setting makes the enemy commanders use much smarter strategies, offering you a more intellectual challenge. However, your allies aren't nearly so clever, consistently making poor decisions and refusing to use any charms of their own. If you get tired of computer-controlled opponents, you can match wits with up to three other players and pit your armies against each other using the PSP's Ad Hoc wireless feature.
