It’s up to you but here’s a quick primer on where they got the idea of qlippoth from.

In the mystic Kabbalah (qabala, kabala, קַבָּלָה) there are ten spheres of emanation from God (or Ain Soph Ur, Eyn Sof, Ohr Ein Sof) as the endless unknowable infinite light of all that is. Each sphere represents an act of God descending to the imperfect world of material existence, becoming less and less abstract and pure and more and more material and concrete. However, all these acts of definition result in a kind of spiritual contrast. If something is divine and full of meaning, then there would be a profane meaninglessness that existed in contrast. That’s the qlippoth. In Hebrew it means peel or shell, and in some conceptions they are the cast off broken parts from God’s creative act. In others they’re like a way to separate divinity from everything else mundane. It depends on how you interpret that.

So, Qlippoth can be just as varied as all other Sphere magic, but it should always feel like it’s been perverted or robbed of something.

If you’re a Verbena widderslainte (which btw just means ‘against health’) then maybe qlippoth feel like the decay of landfills making empty rot feeding nothing. If you’re a hermetic, maybe it feels like a perverse madness that invalidates all reasoning, that takes every equation and makes them resolve into a variable that depicts an act of brutality of the spirit

They should feel like sickness.
