I’ve been reading a bit on Direct magic, which is something I kinda knew was possible but never really took the time to look into. So I have a bit of an idea;
One of the most popular banishing rituals has the mage draw an upright pentagram in the air. The pentagram can be thought of as a general sigil.
So what if I create a more complex symbol to draw into the air and program it to summon a specific ethereal spirit?
The programming, charging and servitor creating/getting might work better with other methods but after I’ve set up everything, I can just draw in the air and summon a spirit binded to me to do my bidding.
I’ll probably start doodling today to see what I come up with.
