Hello KattJessus!
Here is how I would handle it. Inside of the FirstPersonCharacter blueprint find where the LineTrace is cast and try this out. If you also want to be able to blink through multiple elevation levels you would take the z from the break vector use a + node to add your character height to it, and then run that into the z of the make vector. Let me know if this helps!
