Master Seals can be used on any unit Level 10 and above, transforming them into an Advanced class that gains new stats, skills, and the potential to equip more weapons. Advanced Classes also have higher stat growth, so Master Seals are most optimized for use as soon as possible from when a unit reaches level 10.

When & How To Use Master Seals To Their Full Potential

Advanced Classes don’t level up any slower than Base Class units and tend to gain the same EXP from missions and defeating enemies. However, Master Seals enable higher stat levels and growth rates. Because there are no penalties, promoting your units as soon as possible makes sense.

To use a Master Seal to its full potential, you’ll want to use it on a unit to level them into an Advanced Class and then proceed to increase the level of that Advanced unit to level 20 to reach the best stats possible.

This method is beneficial to help in completing the game at a high difficulty level.

Master seals work to develop all Advanced Classes in the game, including any character-specific classes, meaning you can make the most of this item to make the most out of your units.

If you’re heading into a map or battle that seems like it’s going to be particularly challenging, it may be a good idea to use a Master Seal on one of your units before the challenge.

This will give a helpful and significant boost to the stats of the specified unit and help you navigate the difficult obstacles that may come up in that particular encounter.

Chapter 10 is an ideal place to start promoting your units if you are yet to do so. This is likely when your characters will begin meeting the requirements and becoming eligible for promotion into an Advanced Class via Master Seals.

If you have a Master Seal ready to go, the Advanced variation of this unit’s class will be listed at the top of the Class Change menu.

After confirming your selection, you will trigger an animated cutscene that shows off the unit’s outfit and class change, completing the promotion.
