Taking out the transparent crystal from the space ring, Roy looked at it just like he would look at his beauties naked, before he asked,
"Do you know what this thing is, and where can I find it!?"
"This!? Isn't this a Rank 4 stealth crystal!? While these things are rare and expensive they aren't exactly difficult to find.
As long as you have money, you can buy them in batches! One of this costs 10 medium mana stones though, and that it multiplies by 10 for each rank up."
"Really!? This is a great news! Be prepared tomorrow I am taking you out for shopping!"
"Huh!? Why are you looking for these things!? It's not like they are all-powerful. They only work on their own rank, and below.
Every one who is above the rank of the stealth crystal could not only sense your presence but also completely 'see' you without problem."
