Mjolnir (boomerang spell based)

[EyeCandy]

Hi was thinking about my spell is similar to Ahri's (LOL) Orb of Deception
Spell Description
Mjolnir moves at a high speed towards its target (targetable for both Terrain and Single Unit) knocking back slightly any unit it hits and stuns them. Once it gets let's say 2000 units away from Thor, it falls to the ground. Thor can use an alternate ability to summon Mjolnir back mid-flight or after it drops. It also knocks back and stuns when flying back (knock-back in direction of Mjolnir flight). For my map, since Thor loses his hammer while using this ability, he must not be able to cast any other spells or attack. However he can move during the effect of this ability.

I'll take you up on this spell. Do you need it to be MUI (are there ever multiple instances of Thor/the ability Mjolnir in the map)? What ranges and speeds do you want in particular, or can I use what I think is reasonable? Also, do you want it to truly move like a boomerang, or should it move in a straight line toward the target point and back? Is Mjolnir selectable when it is on the ground and/or while it is moving through the air?

Well, firstly, it should be MUI as there are items that refresh cd's so any waits will bug the spell. It does not have to be MPI as there is only one Hero using it.
Mjolnir will move in a straight line if both Thor and target don't move but should be able to curve slightly if the target moves or Thor moves.
Mjolnir should not be selectable as u can ground target or unit target (i.e. it homes). About it speed i think 522 (constant), should have a throw range of 500*Level of Ability, damage for 60+40*(Level of Ability) and be able to damage/knockback all units in ThisUnitGroup while it's being thrown and again while returning to Thor.

Edit: I'm actually trying to adapt Paladon's Advanced Shockwave Spell (http://www.hiveworkshop.com/forums/spells-569/advanced-shockwave-paladon-documentation-110588/?prev=search%3Dadvanced%2520shockwave%26d%3Dlist%26r%3D20) but meh I need to find point in trigger where he kills the dummy and then have a reverse shockwave from the dummy's position.
