The Rukh, also known as BigButrfly, is a powerful enemy in Final Fantasy V. It may use Breath Wing, a Wind-elemental attack; or Zombie Breath, to turn two random targets into Zombies. They are excellent for gil and ABP farming in the Merged World. They are most easily found in the lake near Crescent and Fork Tower, often encountered with a pair of Sea Devils. Like several other late-game monsters, a powerful weapon, the Murasame, can rarely be stolen from Rukhs.
