Some games I noticed that itens that usually has charges when bought, like Difusal or Bloodstone, were inserted in inventory with no charge.
Not all games happens this, but there are countless games that my Bloodstone has no charges when bought. I must confess it does not really bothers, but buying Difusal without charges is not cool (I have faced this once and even buying its upgrade will grant only one stack of purge spell).
I don't have one replay right now, but I will add when possible. Anyway, this is something you should know as soon as possible.
