Macro Help please INT

I need a macro that puts my Muzzle and intimidate in 1 button with a range mod.
currently I have cast sequence with a 15 sec reset. but It gets stuck if target is out of melee range.The wiki’s are helpful but not helpful enough.

With muzzle being a melee range interrupt and intimidation being a range stun/interrupt using a cast sequence macro will not work.

Did you using a modifier macro?
maybe something like. You can change to ctrl or shift if you don’t want alt.

/cast [nomodifier] muzzle
/cast [modifier:alt] intimidation
