Opening rounds applies incorrectly to venator ult

[Orb]

When casting venator ult while having opening rounds, the ult does about 3x the total damage that you would expect. The damage also becomes inconsistent based on the targets max and percentage health in ways I can't figure out.

In addition, sinclair copying venator ult while having opening rounds causes the ult to do around 4x the expected damage.

This is massively increasing the damage of venator ult.

On further testing, the issue seems to relate to the boon scaling of the bonus damage as this bug does not occur if the shot is not blessed, and the damage above intended increases from 0 to ~3x at max level

more specifically, while having opening rounds, each level increases the bonus damage by ~23.5 instead of the intended 3, with that damage varying based on the targets health.
