Lyon: Shadow Prince is back for a Grand Hero Battle! You can find him waiting in Special Maps!
Defeat this magic-craving prince to make him your ally!
There are limited-time special quests available for the active period listed above too.
By clearing the map, you will gain the enemy Hero as your ally.
Reward for First Clear:
・ Normal: Grand Hero (2★)
・ Hard: Grand Hero (3★)
・ Lunatic: Grand Hero (4★)
・ Infernal: Grand Hero (4★), Hero Feathers x 2,000
As with other Hero Battles, if any of your allies fall in battle, it's game over, so proceed with caution. Grand Hero Battles also have a special rule: you cannot use a Light's Blessing or an Orb to continue a battle if you lose, so make your moves on the field very carefully!
Grand Hero Battle Notes:
• The number of difficulties available for a map may vary by each Grand Hero Battle.
• Although the same Grand Hero Battle may be released several times, rewards for each difficulty can be earned the first time the map is cleared.
• If the battle is started prior to the end of the event, you may stop playing and then later resume the battle using bookmark data until two days after the event ends.
• If the battle is started prior to the end of the event but not cleared until later than three days after the event ends, you will not get any of the rewards.
Learning Skills
• You can help Heroes learn skills by going to Allies, then Ally Growth, and then Learn Skills.
• Some skills can only be learned after raising a Hero's ★ rating.

"Ephraim is strong, and he cuts a dashing figure. When it comes to his studies, though... Of course, he did rely on my help for that. I was very glad to aid him."
