It is a notable enemy because, with the exception of Force Field, Grand Delta, Transfusion, and Mighty Guard, it uses everyLore in the game, though it will only use Tsunami when Confused or Controlled. Dark Force can also use Imp Song and Launcher. If Strago has not learned a specific Lore, chances are he can learn it from the Dark Force if the player is patient enough. However, the Dark Force dies when its MP reaches 0, so if the player is still waiting for a specific Lore, it might be a good idea to give it an Ether or two to keep it going.
Since Dark Force is level 55, the player should use Gogo equipped with three Sketch commands. This gives them a 75% chance of using Tsunami, and a 25% chance of using Lv. 5 Death to end the battle instantly.
