Just for some clarification, the word "Warlock" comes from the Anglo-Saxon word "Waerloga" meaning "traitor" or "oathbreaker". If is a term largely used by Hollywood and by fiction writers, but not for actual magic users.
If one is talking about a male Witch, then the term should simply be Witch.
John Constantine is a comic book character from Marvel Comics. Comic books are not a reliable resource when it comes to understanding real magic and real magic users.
Well, if you've seen the show there is tons and tons of real magic and real spells and incantations. Thank you for your help, would you mind teaching me some spells or incantations?
Well then I guess Lamashtu isn't real? Nor is Naamah ? Durgia? Maybe Lilith? I'd argue your point but some of it is fake. But the murr against spirits isn't real? Nor is blood magic or the binding of spirits? Maybe giving away your soul or replacing your own with Pazuzu? I'm just wondering here. I guess they're real, but some things portray it differently than others. Your points are valid but I have a tiny feeling at least SOME of them are real, I hope you know what I am getting at here. I hope I don't come off as rude, luv.
Also, where would I find the materials needed in the spells? Some of them can be found in your normal market but you're not gonna find Wolfsbane in your local market haha.
There may be aspects of real practice, demons and deities in John Constantine comics and the show, but that does not mean that what he undertakes is real magick, it is simply inspired by for effect.
In regards to items for spells, no item is required, you can do without the difficult to find herbs such as wolfsbane, you can actually undertake successful spell work without any items at all. If you are determined to use herbs, etc, in your workings you will likely have to go online to find the more unusual herbs, unless you have a herbalist store or new age store near you that stocks it.
Be very careful in dealing with any spell ingredients with which you are not very familiar. For instance, with wolfsbane, the poison index says " Poisioning from the aconitum plant can occur if it is ingested or handled without gloves. ... Aconitum is also known as monkshood and devil's helmet due to its resemblance to a drawn hood, and is known by some as wolfsbane , because its poison is so toxic that it was once used to kill wolves ."
