[Request] Spell - Hole

Level 2
Nov 10, 2008

I am making a map, and I would like a spell like this:
- The caster target a point in the ground.
- In this point will be created a hole, but only visible to the caster owner.
- When a unit enters in the hole region, the hole will become visible to all and the unit that entered will be stunned for 10 seconds.
- Would be cool if the caster owner receive an alert, like: "A unit has been traped" and one of these "mini-map signals" (The green one in campaing, I forgot the name)
