is there a way to trick comp into casting statis field?

I believe placing an abriter next to an attacking hero unit will force it to cast statis field.

does the unit have to attack the arb? or can it attack just any unit owned by the same play as arb?

has to attack arb, or you have to set an AI, which is finicky at best, and I don't know if it's in there.

i tested really fast, doesnt have to attack arb but DOES have to be a HERO unit.
