I'd say sarcasm is a behavior resulting from an emotion, not an emotion itself, and so sarcasm itself has no place on the emotional guidance scale.

The underlying emotion feels like Frustration/Irritation/Impatience (#10) to me. One can almost sense an accompanying sigh of irritation when someone is being genuinely sarcastic, instead of just being jokingly sarcastic for comedy purposes.

Hi,
Between 9-12, don't you think? I don't know. Secondly, my answer is "sarcasm should be avoided!" I have other thoughts to share, if you'd like my 2 cents worth.
Thanks,

Inconsistent Vibration of Sarcasm
Sarcasm shouldn't be our baseline, should it? Few advantages can be gained by giving off insincerity and pain at a vibrational level, except laughter. Sorry, but sarcasm re-frames things in a way that is funny. This may be speculation, but imagine the sarcastic person's vibration as inconsistent, meaning it's not always at a low resonance. Unless you are a comedian or satirist, it may be better to avoid sarcasm.

Sarcasm as Energy
Comedy, we could dismiss, but if sarcasm goes deeper than that, we owe it a second look. While, it may not relate directly to manifestation, there's a school of thought that believes magic is energy. This is only speculation, but sarcasm could be an essential vibration in shifting our paradigm. We don't like to admit it, but we get stuck in plateaus, policing our vibrations. Please don't take my speculation the wrong way. Rather, consider sarcasm like alcohol, or something that has it's best effects with discretion and measure.

Sarcasm and Fnord
It may sound like "the darkside of the force," but sarcasm is really just energy. Maybe some of these principles could shift one out of a vibrational plateau. Enjoy, and don't take it too seriously. Here's a link that may open up a better understanding of sarcasm and fnord.
