Bael

The Goetia tells us that Bael rules 66 legions of Spirits. His office is to make you go invisible by hiding you away from your enemies.
According to S. Connolly, Bael can help to spark your creativity and even give advice in matters of the heart. Also, you can seek Bael for wealth magick, if you are involved in creative projects, and plan to earn money by selling your creativity.

Morail is a spirit from Grimoirium Verum and also makes you go invisible. You might also enjoy my other post: The Kings of Goetia and how they can help you.
Bael is a very helpful spirit and he helps you to literally vanish so that your presence is undetectable. This is my personal experience.
You may want to use a spell to give Bael very clear instructions. Charge the seal. Give Bael the licence to depart before you close your circle. Keep the seal with you at all times.
Even better, prepare a Witch’s bottle with graveyard dirt and the seal of Bael. Follow this link to the Witch’s bottle with graveyard dirt and the seal of Bael.
Agares

“(2). AGARES. – The Second Spirit is a Duke called Agreas, or Agares. He is under the Power of the East, and cometh up in the form of an old fair Man, riding upon a Crocodile, carrying a Goshawk upon his fist, and yet mild in appearance.
He maketh them to run that stand still, and bringeth back runaways. He teaches all Languages or Tongues presently. He hath power also to destroy Dignities both Spiritual and Temporal, and causeth Earthquakes.
He was of the Order of Virtues. He hath under his government 31 Legions of Spirits. And this is his Seal or Character which thou shalt wear as a Lamen before thee.”
Goetia
Summon Agares if you want to learn a foreign language fast, or when you want to translate your blog into another language. Spells with Agares will make you very fluent in a foreign language.
If you are stuck and your creativity has left you, Agares can push you forward. So, yes, Agares can show you how you can make money if you are an artist.
Well, Agares is capable of destroying the reputation and even the business of your enemy. I believe that the “earthquake” is a metaphor for a huge shocking change or demolition.

Vassago

Vassago is of a good nature and he can tell you about things of the past, and also predict your future. He can also discover secrets, things hidden and lost.
If you suspect that your enemy has cursed you, then you might want to summon Vassago, because he will tell you the truth. This spirits can also give you advice when you are dealing with difficult people.

Sitri

Sitri can inflame men with women’s love, and women with men’s love. This spirit causes a man and a woman to desire each other with great passion.
According to S. Connolly, Sitri can do all the above stated for you, and he can also be called upon when you wish to infuse a creative project with passion.
