Bronze Dice and Muttering Tiara Recommended Party Setup

Character	Best Skills	Explanation
Protagonist	・Zionga ・Mudoon ・Mediarama ・Matarunda ・Rakunda ・Dekunda ・Assault Dive ・Crit Rate Boost ・Eiga	The Protagonist will play a fluid role in the battle, acting as healer, buffer, debuffer, and occasional support damage. He can kill Muttering Tiara with Mudoon, remove debuffs with Dekunda, as well as hit Bronze Dice with its weakness.
Junpei	・Agilao ・Assault Dive	Junpei is your primary damage dealer and will consistently deal single target medium damage with Assault Dive and Agilao. His Theurgy can deal a ton of damage to Bronze Dice.
Koromaru	・Mudoon ・Revolution	Koromaru can deal Dark damage to Muttering Tiara and instakill it. He can also nullify Mamudoon and Maragion cast by Bronze Dice, as well as cast Revolution for increasing crit rates. He is the ideal party member to have in this fight.
Akihiko	・Zionga ・Diarama ・Tarunda ・Elec Boost ・Shock Boost	Akihiko's main job is to use Zionga on Bronze Dice to knock it down for All-Out Attacks. Having Shock Boost and Elec Boost will greatly help strengthen Zionga. Akihiko can also debuff Bronze Dice with Tarunda and provide secondary healing with Diarama.

Bronze Dice and Muttering Tiara Recommended Personas

Persona	Best Skills	Explanation
Girimekhala	・Mudoon ・Dekunda ・Crit Rate Boost	Girimekhala is the perfect Persona for this battle, since it can learn Mudoon to instakill Muttering Tiara and use physical skills to damage Bronze Dice.
Seiryu	・Mediarama ・Matarunda ・Rakunda ・Eiga	Seiryu is a great healer and debuffer for this battle, as well as being able to hit Muttering Tiara's weakness with Eiga.
Dakini	・Assault Dive ・Crit Rate Boost ・Strike Boost	Once Muttering Tiara has been dealt with, Dakini will be great for focusing physical damage on Bronze Dice, while other party members hit it with Electric.

How to Beat Bronze Dice and Muttering Tiara

The following tips can help you beat Bronze Dice and Muttering Tiara in battle.

1. Use Sylphid Aura Before Battle
2. Insta-Kill Muttering Tiara with Mudoon
3. Cast Tarunda on Bronze Dice
4. Use Numbers to Predict Its Moves
5. Use Dekunda to Remove Debuffs
6. Use Therugy Skills for Massive Damage

Use Sylphid Aura Before Battle

Sylphid Aura is Fuuka's navigational skill that buffs your party. Make sure to use it before engaging with this boss, as Muttering Tiara can heavily debilitate you with its debuffs.

Insta-Kill Muttering Tiara with Mudoon

Muttering Tiara is weak to Dark magic so cast Mudo, or better yet, Mudoon to instantly kill Muttering Tiara before it even has a chance to do anything. If you don't have these skills, Eiha or Eiga will do well enough to knock it down for All-Out Attacks.

Cast Tarunda on Bronze Dice

Bronze Dice is the damage dealer in this boss fight, while Muttering Tiara casts debuffs on your party. Use Tarunda on Bronze Dice to lessen its attack power, especially since it casts powerful multi-target skills.

Use Numbers to Predict Its Moves

Rolled Die Number	Skill
1	Maragion
2	Mamudoon
3	Megidola

Bronze Dice shows a die number that corresponds to its next attack. Keep an eye on the number it shows to anticipate whatever it will cast next.

List of All Skills

Protect Against Dark

Having a few Homunculus items on hand will be extremely helpful to stay alive from Bronze Dice's Mamudoon skill, which has a chance to instakill your whole party with Dark magic. If you're all out of Homunculus, having Band-Ace and Revival Bead items handy will also be helpful, as well as the skill Recarm.

Having Koromaru in your party is ideal, since he nullifies Dark magic. Equip Personas that block Dark Magic so the Protagonist will be safe from death.

Protect Against Fire

Bronze Dice casts Maragion, so keep Mitsuru out of this battle and make sure to include Junpei and Koromaru since they are strong against Fire. Equip a Persona that is also resistant to or nullifies Fire.

Use Dekunda to Remove Debuffs

Muttering Tiara casts Masukunda and Matarunda, which lowers your party's accuracy/evasion and attack damage, which is very debilitating. Cancel this out with the Dekunda skill or a Dekunda Gem.

How to Get Dekunda Gem

Use Therugy Skills for Massive Damage

Bronze Dice is a bit high in defense, so keep on using your Theurgy skills to get its HP down quick, before it's able to cast more Mamudoon attacks.
