Yuna dreams about being the hero that saves Princess Fina as she finishes the golem hunting quest for the sake of obtaining mithril. Golems infinitely spawn? The tunnel might collapse if she goes all out? Even a mithril golem? Yuna will challenge it all!
But since the mana gem is valuable, 
it's better not to destroy it.
،لكن بما أنّ جوهرة المانا قيّمة
.من الأفضل عدم تدميرها
Mas as joias também viram recompensa,
então o ideal é não quebrá-las.
