I'd like my users to be able to purchase an item for the first time, and any time after that I'd like it to be upgraded. I'd also like the cost to go up with each upgrade. Is that type of functionality built in, is there a logical way to simulate that without making an entry for every upgraded version of an item?
To Clarify:
User pays 100 gold to buy a weapon for the first time.
User pays 500 gold to upgrade that weapon from level 1 to 2.
User pays 2000 gold to upgrade that weapon from level 2 to level 3.
...and so on
Thanks for the help!
