The latest challenge event in Final Fantasy Record Keeper is called “Touched By Magic.” It’s running from October 14th until October 24th.
It gives you another chance to recruit Terra and Cyan from Final Fantasy VI if you missed them the first time around. If you already recruited them then you’ll get a Greater Growth Egg instead.
If you are able to get their Memory Crystal from the World of Ruin dungeon then you can break their level caps too.
Plus, if you missed out on Edgar and Sabin before, then the two new bonus quests – complete Figaro Castle Elite and complete Mt. Kolts – will let you recruit them this time around.
