Not sure if bug - Acid Arrows on Incorporeal Targets

[spoletta]

Could be intended behaviour, but I will still report it.
When you shoot arrows (without a yew bow) at a wisp, if you are using the acid arrows skill, the arrow finds the target. Both the physical and acid damage get applied.

Is it intended?

[Prometheus]

It is

[Xzait]

reguardless of what you use with a bow, it is hitting incorporeal creatures.
