After that, the player should swap out Martial Arts for Spiritism, for the slowest, and Medication for the others.
Beelzebub (Bravely Default)
This method is expensive, but is one of the faster ways to deal with Beelzebub.
Mimic will duplicate the effect of Dark Breath, but will not consume the items required, expending 3 of both items per two turns.
Finally, one should stock up on or grind for Demon Tails and Dragon Fangs. Beelzebub's attacks include Octowhip, a physical attack that hits the entire party, and Firaja.
