What does upgrading unique leaves do?
I spent some cosmic essence on upgrading my ghost leaf to get more blc, and when I upgraded it, the question mark pops up. Hovering over the question mark says +50% blc value at first, then I upgraded it again and it said +100% blc value. What does this mean? Does this mean the leaf gives a total of +600% blc value? (500% base + 100% upgrades)
