is it possible to do this...if so how

I wanna spell that fires 3 balls staight ahead....
one fire ball one ice bolt and lightning how would i go about doing this? is it possible?


it would be an attacking spell so i dont want 3 dif damages or anything just want it to look like its casting 3 "bolts" at the target

yea...i think u can do it thru trigger

make 3 invis unit that spawns and order them to attack target (with different missile art)
