Chain Challenge (連戦トライアル, lit. Series of Battle Trial) is a special game mode from Fire Emblem Heroes in which several Story Maps are chained together and must be cleared in a row to earn Hero Feathers and Orbs. To unlock a level of Chain Challenge, the corresponding Normal mode of Chapters must be cleared in the Main Story/Paralogues.

Rules Edit
Choose Your Difficulty Level Edit
There are several difficulties to select from, and whether you want to complete a single or double Chapter/Paralogue, so select the difficulty level that best suits your allies:
| Type | Stamina | Teams | Battles |
|---|---|---|---|
| Single Chapter | 20 | 2 | 5 |
| Double Chapter | 30 | 3 | 10 |
| Single Paralogue | 20 | 1 | 3 |
| Double Paralogue | 30 | 2 | 6 |
Defeated Allies Can't Be Revived Edit
If all of the allies on your team are defeated, you can immediately make a new team of allies and try the map again. However, be aware that the allies that were defeated cannot be used again until either the last map is cleared or all your teams have been defeated and you try again. Try your best to come up with strategies that will allow you to advance without sacrificing your allies. Be aware that your allies will continue to the next map in the set with the same HP and cooldown as when they finished the previous map.
It's a Battle or Attrition Edit
If you try a map again with a different team of allies, the enemies defeated by your previous team will not reappear. Any surviving enemies will carry over the HP they had before, and their Special cooldown will reset. Even if you didn't damage the enemies with your previous team, their starting HP will be reduced by 20% so they will gradually become easier to defeat.
Rewards Edit
Rewards are based on difficulty and whether you complete a single or double Chapter/Paralogue.
| Type | Normal | Hard | Lunatic |
|---|---|---|---|
| Single Chapter/Paralogue | 200 Hero Feathers | 400 Hero Feathers | 2 Orbs |
| Double Chapter/Paralogue | 400 Hero Feathers | 800 Hero Feathers | 4 Orbs |
