Evocating the supernatural

Hello all, I would like to have someone help me. I’m planning on doing my first evocation with Azazal and I’m not sure what to suspect. If anyone else has evocated him can you please tell me what he is like when evocated. Also after I evoke him for awhile I would like to try my hands on evoking a angelic being to help me learn some simple healing spells and possibly find out how I could bless some objects to help me heal others. If anyone has anything to help please say so.

There’s many threads on Azazal if you search. As for angels idk.
