Forgot the Title

#1
I don't have a lot of information to go on for the story.  From what I remember is that the story had a male character in a fantasy like world with litRPG elements.  He wanted to become a necromancer, but instead he becomes a warlock.  I also remember that he makes a contract with a wind elemental as well after going to a mansion with his "Mentor" and fighting some skeletons, also, he was going to get a different spirit to contract and I believe the other one was a banshee of some kind but the mentor banishes or kills it off instead.  I also believe that he was in game and split up with his friends with some sort of promise to meet at a city somewhere else.

Thank you for your guys help, and I'm sorry that I can't provide more information
