How to Change to New Classes

Last Updated:
To change classes, all characters in your party must take and pass the Certification Exam. This option is only available in the activity selection screen. When at least one of your units is viable for promotion, an exclamation point will appear beside the Certification button.

There are different tier classes and it’s imperative to eventually have your units get promoted to the higher-tier classes to increase their Stats and growth rate through Skill EXP bonus. Mastering their respective classes will also unlock new Abilities and spells that your characters can freely equip/unequip even if they change classes.

Take note the unit’s skill level will affect his/her odds of passing. If the odds of passing are below 30%, a unit can’t take the certification for that particular class.

This activity doesn’t consume any Activity Point so take your time in certifying your characters eligible for certification. Kindly check out our guide for the skill requirements for the higher-tier classes so you can plan ahead and develop the characters you want to change to certain classes eventually.

Here’s an overview of the requirements to change classes:
1. Reach the required level
2. Reach the minimum required skill levels
3. Have the necessary Seals in your inventory.

Seals are Required for Certification

Seals are consumables that are required to promote a unit to another class. If your unit fails the certification exam, the used seal will not be refunded so I suggest saving your game if you’re planning to have a unit take the certification with less than 100% chance of passing. Seals will still be required just in case you a unit to get certified to another class, regardless of tier.

You can buy any number of Beginner Seals from the Item Shop. Other higher-tier seals can also be purchased in limited amounts per month from the item shop or other players via the Traveler (online) feature of the game. More seal types will become available as you progress in the story.

Class Tier Level Requirements

Each tier has a minimum level required before the exam for that level becomes available, as follows:
Tier Min Req Level
Beginner LV5
Intermediate LV10
Advanced LV20
Master LV30

Male-Only Classes

Class Tier Required Skills
Brawler Intermediate Brawl
Dark Mage Intermediate Reason
Hero Advanced Sword, Axe
Grappler Advanced Brawl
Dark Bishop Advanced Reason
War Master Master Axe, Brawl

Female-Only Classes

Class Tier Required Skills
Pegasus Knight Intermediate Lance, Flying
Falcon Knight Master Sword, Lance, Flying
Gremory Master Reason, Faith


Once a unit passes certification, his/her new class is considered learned permanently. You’re free to change a unit to any class he/she has been certified with. However, this can only be done in the Battle Preparation screen. Access the Inventory option and the Reclass option will be at the bottom.

When you select this option, all the available classes your unit can change to will be displayed. Re-classing doesn’t consume Seals so use it as needed, especially if you want to switch to a certified class the unit has yet to master. A unit’s mastered class will have a star icon in the upper-right corner of the class sprite.
