(warlocks) do you use nightfall? If so how do you macro it?

I was thinking one way to use nightfall would be to put shadowbolt at the front of a dot macro (I.E. /cast shadowbolt /cast corruption). If you use the macro while walking, it will dot the target, since shadowbolt doesn't cast while walking. However if nightfall is up, it will shadowbolt instead.

That way, if one of your toons procs nightfall, you can hit the shadowbolt button, and the other characters will cast corruption.

Can anyone else think of a better way to go? Some kind of conditional [if i have this buff cast this thing] [if not cast this other thing]

I'm not sure having two spells in a macro using /cast that trigger a GCD will work the way you want it.

I believe all a macro with /cast Shadowbolt as the first line will do if you use it while moving is throw errors at you about how you can't cast that while moving.

I think the general rule is that the first /cast that triggers the GCD is executed and the macro is considered "done" regardless of whether the /cast was successful.

I think that you may have to have a separate key for shadowbolt that you simply spam while moving or just when you hear the sound of the nightfall proc. Personally I'd go for the sound option, since even if you have sound diabled on your alts, your main can still hear their proc.
