Fina discovers that her current iron knife can't cut through the tough fur of the black tiger and Yuna takes her to get a stronger replacement. However, Yuna finds out about the existence of mithril at the blacksmith's and begins a quest to obtain it!
And the harder it is to get my 
hands on it, the more I want it!
!وكلما كان من الصعب الحصول عليه، زادت رغبتي فيه
Außerdem will man etwas, das schwer zu
bekommen ist, doch umso mehr haben!
Et plus c’est difficile à obtenir,
plus ça me donne envie d’en chercher !
E poi...
Além disso, quanto mais difícil,
mais queremos!
