That's when you have 0 or less than 6-8 stacks on the target. Since every wave stacks impure shots (up to a maximum of 8 stacks), the damage will increase.

However, if you stack Impure Shots on your target before you use your ult, as I said before, it will directly apply max stacks with every wave.

In short: you can either use your ult to apply stacks or apply stacks to get maximum damage from your ult.
