1. High Templar - Feedback (Damage Target based on Energy) -> Flags -> Tick "Kill".
This will kill the targeted unit.
2. Set the ability's target filter to allow targets without energy.
3.Copy the "Has Energy" validator. Change type to "Maximum", set Compare to "Greater Than" and set Value to "0", set the failure result to "Must target energy capable units" and set the "Result - Failure" to "Must target energy capable units", too.
4. Add that validator to the feedback's effect set.
Feedback removes all energy from a unit and deals damage according to that amount.
I would like it to instead kill a unit with energy completely, no matter if it has 0 energy or full energy. (But it must be an energy unit!)
How can the current feedback be modified to do this?

That's it.
You can also use unit filters to require that the target Can Have Energy.
