《最终幻想 世界》求问马丁的记忆在哪里得到

@linxuan 找到了么，我也缺这个。。

我發現好多人問這個。。。我去翻了官方攻略，是一開始綠妹子召喚的那個嗎！
官方內容如下：
OBTAINING THE HIDDEN MADUIN MEMENTO REWARD
In “The Five Cogna Lords: Figaro” Intervention quest, a hidden cutscene involving Maduin, Terra’s guardian Mirage, can be unlocked. To unlock it, you not only have to win the Sandbattle mini-game, but you have to win it in fewer than 20 total turns without losing a single unit. This can be a considerably difficult task, so keep trying! After you defeat the consequent Cogna encounter, a cutscene between Terra and Maduin plays out. You’re also rewarded with the maduin memento (a transfiguration from a titan Mirage).
簡單來說，就是心靈任務中魔導戰士小遊戲你必須20回合內獲勝，而且任何單位都不能死。然後隱藏的馬丁就出來了。。。
