Ok, I see now. You are raising these in the editor which means they are spawning at that height and then raised about 1.5 metres in the script, when they exit they are dropping the 1.5 metres though you probably aren't noticing this
If you want the character to fly higher then change the following setting in the init part of the script to height you want, I think the values are in mm. And always place the character at ground level in editor.
function ai_wraith_init(e)
MoveUp(e,1500) change to
MoveUp(e,5500) or whatever height value you want.
Now when your character dies it will fall all the way down, tested it and works as it should, hope this fixes it for you. Any other issues don't hesitate to let me know
Edit* If you are good with scripting you could change height values to drop on player during attack etc, I reckon using height linked to player position in the script could even have this character follow upstairs etc since he doesn't use collision while active, he's an interesting one for scripters to play around with
