Interesting Quirk On Invisible Units

I don't know if this has ever been posted, but I noticed an interesting quirk related to permanently invisible units.

It seems that you can create completely invisible units, using a Perma Invis ability with 0 duration, and share vision with a player. That player can interact in some ways with the unit, attacking, casting spells and the like on them.

Even better is that when you use the Dummy model used in the caster system the special effects from the ability will actually play the special effects of the spell being cast on it.

Dunno if this is useful, but I am sure that someone will find a useful use for this.

Oh and there is no annoying effect that I came across sometimes with the dummy units getting an arrow from shops over their heads.

If this was already noted someone please feel free to delete this post some mod.

Haha, I knew this a while ago, but still fun to know.
