- As of now, this is a limited-time opportunity to summon these Special Heroes. They may or may not appear again in a summoning event held in the future. Please note that they may appear at a different rarity or at a higher appearance rate.
- Heroes with different illustrations and epithets are treated as different Heroes even if they are the same character. As such, you cannot use them with Merge Allies.
- To see more summoning details, tap the Appearance Rates and Details buttons on the Summon menu.
- You can help Heroes learn skills by going to Allies and then Learn Skills.
- Some skills can only be learned after raising a Hero's ★ rating.
- Heroes might have already learned some skills based on their ★ rating when they joined your team.
