Here's something we didn't explicitly mention in Asteria although it should be obvious to anyone practically involved in occult affairs who also studies astrology. It should be of no surprise each planet feels differently when transiting different zodiac signs.
By extension, its spirits, when called upon in ritual, manifest differently depending on the sign the planet is transiting at the time. We've discussed this from a different perspective in Asteria in the section on natal chart and I also addressed it from the same perspective in Words. It also applies to other spirits of forces found inside the zodiac chart, such as spirits of the signs, but in this case it has to do with sign placements or lack of (among other things).
I will simply resume to discuss the planets since many work with their forces. The person conjuring their spirits needn't be psychic in order to see or hear those spirits to be able to notice them differently depending on the sign their planet transits at the time of the ritual. With a bit of concentration the person can sense a different vibe to them after their arrival. This takes place after the conjuration and can last even after their departure, due to residual energy.
Naturally, each planet's spirits would manifest the vibe of their planet, but they would do so based on the state of that planet. For example, if you call on some planetary spirits when their planet is strong in the heavens, their spirits would show up giving vibes of contentment and confidence. On the other hand, if you'd call on them at a time their planet is weak, they would come across as irritated, annoyed, even distant or cold.
I wrote this article about planetary strengths and weaknesses so feel free to look it up if you want to go ahead and test whether I'm talking out my arse or not.
