I’ve worked with Forcalor and evoked him several times. I did get guidance from @meow and @QueenMustang last year on Forcalor.
I will not go into the baneful aspect on a public Forum, and you’ve got some really good info shared on here.
But I’ll say this on record. Forcalor is one of the bad boys of the Goetia and is extremely effective and quick. He does have a sense of “righteousness” about him. So if you’re calling him to eliminate someone make sure in your head atleast you feel they deserve it.
Apart from Baneful I’ve been helped by Forcalor on removing a 4 generation bloodline curse.
As suggested by @meow Focalor is one of the Goetic Spirits I’d think twice before using Solomonic methods with. Just speaking from what I’ve known of him and what he’s told me. But you do what works for you. This is just my opinion.
