How to Beat Iron Dice and Silent Book

The following tips can help you beat Iron Dice and Silent Book in battle.

1. Use Sylphid Aura Before Battle
2. Hit Both Bosses with Their Weaknesses
3. Cast Debuffs on Iron Dice
4. Use Numbers to Predict Its Moves
5. Be Ready to Cure Distress
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 Silent Book can get Iron Dice's damage out of control with its constant buffs.

Hit Both Bosses with Their Weaknesses

Iron Dice is weak to Ice, while Silent Book is weak to Wind. This will be a relatively easier fight. Hit both these weaknesses to trigger All-Out Attacks until they perish.

We recommend bringing in Mitsuru and Yukari for this battle. However, if you have access to Personas that can cast Garula and Bufula, you can bring any party member you wish.

Cast Debuffs on Iron Dice

Iron Dice is the damage dealer in this boss fight, while Silent Book provides buffs to its ally. Use debuffs like Tarunda, Rakunda, and Sukunda on Iron Dice to negate Silent Book's buff on it. Debuffing is necessary, since Iron Dice casts very powerful Strike skills.

Use Numbers to Predict Its Moves

Iron 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

Be Ready to Cure Distress

Iron Dice casts Eerie Sound, which may inflict Distress on your whole party. This is easily cured with a Me Patra skill, which Yukari learns. You can also alternatively use Me Patra Gems or Patra Gems

Status Ailments Guide

Use Therugy Skills for Massive Damage

Iron Dice is a bit high in defense, so keep on using your Theurgy skills to get its HP down for a quick fight.
