Strafe type Abiltiy

This may be a n00bish question but when it comes to trigger spells thats what I am; how could i create a skill that gives a unit the ability to launch multiple missiles when attacking. PLease don't flame me if its simple or something, I really need to know. :(

Do you mean like the multi shot ability in http://www.wc3sear.ch/?p=Spells&ID=104 ?

That would be perfect if it only could be an autocast ability, but well il take what i can get. ^_^

Either a modified barage or give it a modified lightning orb ability that has 0 modifers, but a 100% chance to cast cluster rockets instead of the units regular attack.

Both of those are autocast.

Actually those are passive

Well, you can use the modified orb ability and then when the autocast is turned on you can switch the abilities to the working one, and vice-versa when it's turned off.

Use parasite as base for the triggerer ability for my spell and done

very, very decent.
vexorian, you wouldnt mind me using that for my campaign would you?
ill give you credit
<congrats on your 2000 posts too :D >
