Use the following items/skills obtained from beating the various bodyguards when the warlord begins to use his dirty trick on your character. Note: You must be quick when the warlord begins to use his trick, as the only way to steal it is to suffer no damage during its use on your character.

Earth Warlord: Earthquake (use Jade Turtle of Longevity)
Fire Warlord: Fireball (use Iron Lotus Shield)
Wind Warlord: Hurricane (use No Shadow Stance - the slow motion item)
