Eiko Carol is one of the playable characters that joins the party in the second disc of the game. She is the only person who appears in the game with a Summoner's Horn. While Eiko and Garnet both share White Magic and Summoner abilities, Eiko uses primarily white magic with her summoner powers taking a secondary role, indicated by the order of said skills on the battle menu. Her summon abilities are usually holy-based summons or summons that add supporting effects. Some examples are Phoenix, which revives all unconscious party members, and Madeen, which causes Holy damage.
