On another forum, an individual brought up a good point. I will echo my response to him, here:
Yes, it is true that these spirits are capable of far more than just performing their function. No, that is not the only function they have, or purpose they serve. For instance, you can use Naotabas in a love spell, and unless you want the object of your desire to begin adoring you from your actions as a shoulder to cry on for her as her entire family is murdered, you’d be better off asking someone like Vorcalis.
An example of this would be with Shotab, before I knew he was a warrior entity. I asked him to assist me in getting a raise at my 9-5 at the time… and instead, the company collapsed.
Upon evoking Shotab to ask him what exactly went wrong, he described to me the levels of corruption at the corporate level, and since he had unsuccessfully tried to cut away at the corruption enough to find a raise for me in there, he decided to tank the entire corporation.
Thirteen days later, I got a more specialized job offer, from a different company, which was paying nearly double what I was offered from the company Shotab slew.
When I asked about who had my previous position, a coworker told me that roughly four days after Shotab’s summoning, and the day after the company collapsed, my predecessor was killed by criminals in the city he had gone on vacation in. Two men mugged him, and when he tried to fight back, he was shot in the stomach.
So those are just some examples for you to chew on.
