Skill Help (Multiple arrow/strafe)

i have absolutely no idea how to make a Multiple arrow skill like in ToB, or strafe in the Diablo Duel map, (they are the same thing for you people that have only played one of the above) just tweaked
i am fine if it involves triggers (which i am an expert at)

for multi arrows, make an ability based off of barrage. and change targets

ah i see, i never knew what barrage was lolz i thought it did something else, but ok thx
