Custom Class Code Help

[sepchamp]

What is the code to cast a spell only if I don't already have its aura (Horn of Winter)?
I know for example that with howling blast I can make it only cast it when I have freezing fog like this:
return new Decorator(ret =>
(Me.ActiveAuras.ContainsKey("Freezing Fog"),
but I need the opposite for horn of winter to cast it only when I don't have it up. Thanks

You'll have to tell us what CC you're playing with (or what framework), as they each have their own methods.

(!Me.ActiveAuras.ContainsKey("Horn of Winter")) ?
