Applied Effect Duration Count Down Timing
Question: Are the only times that an applied effect duration counts down at the start and end of the round?
For example: I have an effect that adds enfeebled: 2 to a target until the end of the target's next turn. When I set the effect up in the Actions Tab, I can set the effect to apply to TARGET, ALL rolls, and either START or END of turn. I can change the "Initiative to adjust on" in the Combat Tracker as the GM which I believe will have it count down at the appropriate initiative count but my player's can't make that change. My player's are very fond of applying effects so anything that makes the application of effects faster is greatly appreciated.
Is there an obvious way of having effects count down at the appropriate time though automation?
Thanks in advance!
