First, let me define my terms:
Lovecraft's: By this I mean only the stories written by H. P. Lovecraft and him alone. I am not including his revisions of other author's works or the stories written by August Derleth based upon plot germs in Lovecraft's notebooks.
Cthulhu Mythos Stories: I'm pretty strict in this definition. I recognize only the following eight stories by Lovecraft to be part of the Cthulhu Mythos (though there are many Cthulhu Mythos stories by authors other than Lovecraft):
The Call of Cthulhu
The Dunwich Horror
The Whisperer in Darkness
At the Mountains of Madness
The Shadow Over Innsmouth
The Thing on the Doorstep
The Shadow Out of Time
The Haunter of the Dark
Only two of these stories have any magic spells in them: The Dunwich Horror and The Thing on the Doorstep. Here is a listing:
Spells in The Dunwich Horror:
1. Summon Yog-Sothoth
2. Dho Formula (reveals the inner city at the two magnetic poles)
3. Dho-Hna Formula (takes one to the inner city at the two magnetic poles)
4. Sabaoth (summons creatures "from the hill and not from the air")
5. Powder of Ibn-Ghazi (reveals invisible)
6. Voorish Sign (reveals invisible)
7. Banish Spawn of Yog-Sothoth and Human
Spells in The Thing on the Doorstep:
1. Immortality (allows a soul to steal the bodies of others)
2. Defense (protects one from the Immortality spell)
That is it. Lovecraft obviously made very little use of magic in his Cthulhu Mythos stories. If any CoC gamemasters want to model their games' magic system after pure Lovecraftian Cthulhu Mythos, I suggest using only the above spells, and even then only rarely.
