Any Shockwave or Line Damage Ability That Can Harm Allies?

Is there any shockwave-type ability that will damage allies by selecting in the "targets allowed" for it to damage both enemies and allies? because any spell that i can think of that is a line-damage ability always seems to ignore allies no matter if i tell it allied or friendlies.

perhaps there is another spell?

If not, you can always just trigger a dummy unit (that belongs to an enemy of the caster) to use another shockwave towards the same target point.

No you can't Anopob. Suppose 3 different players (eg FFA) exist in the same location, someone will get hit by the shockwave twice.

No, just trigger it. It's very simple to achieve if you're even moderate in triggering/coding.

Meh true I guess.

i got an idea, give the unit a dummy ability, and then wen its cast create a unit for hostile with ability and make him cast, that way u dont get a double shockwave, or just add a function determining who isnt in the area and use them as the basis of the cast.

Already suggested by Anopob. It's a sub-par solution.

Just trigger the whole effect.
