Banished (Region) System Needed

[Gausslander]

I need a system for my map where if you enter a region, you become banished.
1-This will require the banished graphics
2-This will make it so you DON'T take damage from spells
3-I need it so when you do enter the region, a text goes above your head that says: Temporarily Banished, in green letters.
4-This should make the unit totally invulnerable
5-The units that enter this region will be ground units, so they should become air units when they enter the region.
6-I've already set air pathing blockers around the region
7-That's all, I will give you credit if you make this spell for me

Add (invulnerable) to the unit when they enter it, and create a dummy that is then ordered to Banish the triggering unit.
