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 Land Crawler 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.
Because it is found in the desert outside of Phoenix Tower and it drops (Elixirs), it can be used to farm Elixirs for the Elixir-thirsting enemy inside the Phoenix Tower, the Magic Pot.
