Item Drops and Finds Version 2 - Post BB

So JMS had an event where you get a box at the beginning of the event, and every day you can use it and either turn it into a better box, or an item. After 3 upgrades, you are forced to get an item. Most of my characters got a 50% Goodness Chaos scroll (Or whatever they're called, they only give good stats), while my Paladin got this.

In case you can't read it, it's a 5-star Potential scroll. I have no idea how rare these things are in GMS, but in JMS you can only get them through a few events. It's a 50% chance, pass or break. If it passes, my item gets 5 stars instantly.

I'm not sure what I'm gonna do with it. When I first saw it I considered buying a Shielding Ward, and using both on my Sword...however it seems that Wards were removed in JMS, I can't find them in the Cash Shop. What to do... Someone's blind. I found them. I guess I'll save it for the next time I buy Points, and cross my fingers.
