Summary
The Fire Emblem series is known for its permanent death system. When a Player Unit's health reaches 0, they die and can no longer be used in any future battles unless revived under special circumstances. Like Casual Mode, Phoenix Mode is designed to make the game easier on players, especially for those who wish to experience the full Fire Emblem story without having to restart a new playthrough if the game proves to be too difficult to progress. If a unit's health reaches 0, they will be temporarily incapacitated for the rest of that turn and the next Enemy Phase. Upon the player's next turn, all units whose health was 0 is instantly revived though the amount is currently unknown.
