Targeting Spell (Dark Spell)

Explanation:
How this spell works is when it is placed troops that run into the area are able to be temporally controlled. Meaning that you are about to select either a building or just a general area where you would like to troops to go.

This would be wayyyyy too OP:
To stop this spell from being way to OP here a list of things you would and won't be able to do:
- Once you have selected where you would like the troops to target, it is locked in and can't be changed.
- This does not make them walk through objects (buildings, walls) they will still need to destroy walls that obstruct the object
- Once the troops have destroy the target they go back to normal state
- You can't use the spell more than once on the same troops


Information:
It would be a dark spell.

Feedback/Suggestions:
Let me know what you think and what better additions/ideas/suggestions you have for this spell!

Good troop placement essentially does this anyways. People would just start setting it to town hall, once they were within range, and easily win attacks. Using it to target single defenses isn't really necessary, since they generally go down anyways once troops are within range of them. The only defense worth using it on would be inferno.
