Help with spell trigger

[ZilvaX]

How do i add a buff to a attack? and can i put a buff on the skill chain lightning?

Well, with chain lightning leaving a buff you're into things like dummy casters.
Unfortunately, buffs can't be applied with triggers so you have to use hardcoded wc3 abilities as a base.

Now, I'm on vacation and don't have my world editor with me so I can't give a 'play by play' of what to do.

Though, there's a few tuts out there but if you want to keep it as simple as possible--do what works for you.
You could try that group thing out.

Well, dont you agree that my way works Aero? I mean since he doesnt know how to do buffs its the best way for him do use it right? not unless he wants a space saver

Sure it works--but it would be way more efficient if you used "Player number of owner of ..." instead of checking for each player.
