Imp is an enemy in Crisis Core -Final Fantasy VII-. It mainly uses Fire-based attacks, so equipping Blaze Armlet will help. Graviga, followed by Costly Punch or Assault Twister+, work well. Its Ultima spell can be guarded against, or the player should have MBarrier active, or time a roll perfectly to avoid it.
imp is "a small, mischievous devil or sprite."An
