im just wondering what it does as it says "Use on Ignored"

but the description doesn't really say.

i think if you use it, it's a stat booster. *needs confirmation

ok... im not sure if i should try. what do you think?

It's a stat booster, but there are much cheaper ones out there. You can also combine it with items to make awesome weapons. Mosey on over to the battle forum to see the combos.
