Cause an effect on a failed/succeeded save

[galnewinhaw]

Is there a way to have a spell cause an effect to occur when a saving throw is failed/succeeded? Currently I have to do the save, and then if it fails separately run the effect.

An example is the first level spell Bane.

I'm using D&D 5e.

Thanks!

No, you are doing it correctly. FG can't automatically apply an effect on a failed save.
