Unit Area - Making melee units attack a short-distant unit

[Anubisath]

Hi i got a Problem with the Area of an Unit.



I want this Unit to stay in the Middle of the Pool so i set its Movementspeed to 0 (hope this is the right way to do this).

Now just my ranged and caster units can attack him.
But i want that my Melees can attack him too.

Can some please tell me how i can enlarge the greed ring up to the red one?

(I'm german so sry if i dont found the right words)
