Chapter 20: The Dawn's Eye
Chapter 20 focuses on gameplay mechanics and unit management strategies. In the _Fire Emblem_ Cipher card game, characters from this game often excel at swarming opponents with cheap units. A notable mechanic for Red cards (excluding Lianna and Rowan) is the Hero Skill, which allows the main character to change mid-play.
For unit retention, _Fire Emblem: Shadow Dragon_ features side chapters (Gaiden chapters) that activate if a certain number of units are lost. These chapters provide new recruitable characters, preventing the player's roster from becoming too depleted.
To ease difficulty, _Fire Emblem: New Mystery of the Emblem_ introduced Casual Mode, where defeated units are not permanently lost and return in the next chapter. _Fire Emblem Fates_ offers an even more forgiving option with Phoenix Mode, where defeated characters return to battle on the very next turn with full health. These modes cater to players seeking a less punishing experience.
In _Fire Emblem: The Blazing Blade_, Lyn's Tale acts as an introductory tutorial. Units defeated in Lyn's story are not permanently lost and return in Eliwood's/Hector's story, though they will be weaker than if they had not been defeated.
