A bad talisman?

[SakuraHynan]

So, I am playing this game, I'm at Fire Mountain now (after Moon Village) and a woman gave me something that she says is a talisman, to protect me. But when I used it, it consumed my mana. xD

This "talisman" will be useful for anything in the future, or it's just a bad talisman that doesn't help me? >_>

Evil old woman.
