Landcrawler is an enemy in Final Fantasy V.
It may use Crush, which will inflict critical damage and Confuse a target. Its other dangerous move is Maelstrom, which reduces the HP of the party to single digits; capturing the Landcrawler will enable the player to use this skill.
A popular and effective counter to the monster's high health and decimating abilities is the casting of Level 4 Graviga quickly followed by Aqua Breath, which causes catastrophic damage to Desert-type enemies. Another way to end the fight quickly is to simply use the Black Magic, Death, as it is not immune to it.
