Bleed target building

I have a spell called "Bleed" in my map, when u presses the button it makes random bleed on units. Only one at the same time... In the reallity it summons an invisible water elemental with inbisible projectile arts but it attacks buildings and buildings can't bleed (if u didnt know that). I think it is very strange because I made the attack limit to "organic, ground, air" (NO MORE!!!). Do u have any idee what to do?

Buildings shouldn't count as organic unless they're night elf buildings. That is a little odd, however.

Try unselecting Air and Ground (selecting both is redundant; these are target limiters), and selecting Unit. Structures may still count as units, but they also count as Structures, which you've left unchecked.

Could you be more specific on the function of the ability?

Is it a click, then target ability? Like holy light? Or does it just make random units around the target bleed?

You could make the invisible elemental attack type "magic" and give the buildings some magic immunity... That's my suggestion ^ ^

I thinked a bout make them magic immune but I have other magic spells against buildings and other units with magic damage, that would disabled other spells and attacks too. And structure IS unchecked but I think it is some kind a thing that doesnt work to uncheck because when I select "enemy, neutral in the attack targets it is still possible to attack friend. Is there any kind of non-structure-button?
