Cast Fireball, when the debuff "Frost Nova" is on the target

[Sîrwildboar-patchwerk]

Heya!
I already try some, but cant get it running!
Something like this maybe?

/run if UnitDebuff(“target”, “Frost Nova”)=1 then /cast Fireball else /cast Frostbolt(Rank 3) end

Edit: Playing on Classic.

Not possible.

3. Macros - What can they not do?

Macros cannot make smart decisions for you. They can’t cast spells based on cooldown, or check if a buff is active, or magically fit all your abilities onto one button.

Okay Thanks!

I read online, that you can use LUA Scripts. Whare can I put my LUA Script and USE the LUA Script in a Macro?

You cannot use scripts to cast spells.

If you’re trying to use it for other things it just goes in the macro window or into an addon.
