Hello!
So what are my personal comments about this?
Well, I think this spell is kind of useless sorry...
Might be found to be useful for some players but well, as I said, my personal thoughts.
I could not find any leaks and you have a good documentation (like that!

You could make the effects a bit nicer and maybe add some functions to the spell, other than that: Good job!
Other than that:
-
Can this be approved?
- I can see no reason not to approve this
How can I solve this problem?
- Well the only "problem" I could find is that this spell is not really "something else". Maybe add some effects and add a few extra functions such as: The targeted unit should be dragged closer to the caster and be stunned under that time.
Not a problem, your spell do as you like

To get a full rating, make the effects nicer and add a few functions.
The spell is leakfree (as far as I can see) and is MUI.
