I used this ritual (mostly) to summon him because he seemed like someone who could help me at the time. It was a very powerful experience, probably the most powerful and successful summoning I've performed.

The description of him is correct but also completely wrong. I think he's actually a higher god who prefers to live in the underworld by choice, not because he's limited in any way. Not at all the sad guy he's said to be.

I think you need to be very serious and should only contact him if your request is sincere and urgent in some way.
