Request for Archer spell

Request for Archer spell

I need a passive spell for archers which makes them fire inaccuratly. I have tried using tinkers spell as a base however that does damage in the area over time much like blizzard only more often.

This is the sort of thing I think might need to be done in triggers, but I don't know how to do it. I would like to be able to change all the things in brackets and so changing the inacuracy of the archer and make differnt types of archer.

The archer projectile is invisable and instand with no damage
Trigger = any unit is attacked by {archer}
Actions:
-special effect {arrow} is created
-last created special effect goes from {archer} to (attacked unit) with random offset between (500,500) and (-500,-500) with speed of (700) and arc (0.30)
-units within (50) of offset take (10) damage

Maybe you can try lowering the projectile speed and setting the projectile homing to - False. Base it off barrage.

Well they all end up aiming for the same target, What I'm after is somthing more like the Warhammerark Omen archers. Heres a piccy of the arrow thing I'm after http://www.computerandvideogames.com/screenshots_library/dir_12/vortal_pic_6177.jpg

This skill is going to be used so that a large number of archers all fire at the first guy they see, however almost all the arrows miss that guy but may hit others.

Oh, just use the Tinker's Cluster Rockets ability and set the stun time to 0.01
