Astrological Magic is my main spiritual practice, so it pleases me to see someone post something about it on this forum. So good to see this stuff spread!
The Picatrix is THE source for stuff like this. You want to have the target planet in an angle, unafflicted, and in their own dignities. You want the Moon in good shape too; not applying to malefics, not in Scorpio or Capricorn, not with the Nodes, not conjunct or opposite the Sun, and not in the Via Combusta. Some people say it's also good to have the Moon applying to the target planet, and I tend to agree. I also consider Whole Sign aspects out of paranoia. Planetary Days and Hours matter as well. For Jupiter I'd go with a Thursday.
Your focus should be on getting your target planet as strong as you can get it, and protecting the Moon. This is like reverse Horary, so you need to focus on the relevant factors. Don't start focusing on everything.
In your chart you have Scorpio rising, ruled by Mars in Libra. Not good. Waiting until Sagittarius was rising would have been ideal as it would have put Jupiter in the 1st house, angular, ruling the 1st house and being generally very positive and full of all of that lush Jupiter goodness. Mars is applying to a sextile with Jupiter, which isn't exactly a deal breaker IMO. I'd be much more worried about a square or opposition. Plus Mars is the Asc ruler, in bad shape applying to a positive Jupiter. You see a bit of a narrative here.
You have the Moon in Pisces in a Whole Sign reception with Jupiter. That's nice. The Moon is Waxing, which is good for talismans. Her next aspect is to Mercury who is retrograde and combust, but angular. This is called "Returning". Basically the Moon wants to do something (in your case make a good talisman) and passes it off to Mercury, but Mercury is retrograde and hurt by being too close to the Sun, so he passes it back to the Moon, a little beat up too. However since Mercury is angular and the Moon is succeedent, things can still move forward.
So it's not the BEST chart for a talisman. I would probably avoid it to be honest. A talisman is nothing but locking in the nature the time to an object. In your case you'd be locking in the nature of Mars in Libra in detriment, out of sect, applying to Jupiter. That's a rocky, unstable situation that becomes something decent....or at least acceptable. The Moon is saying the same thing; trying to move forward with something, it not going that well, but coming out on the other side with something at least passable. That's not something I'd want to lock into an object and carry around with me. This isn't an absolutely terrible electional chart, but I'd be wary of using it for a talisman.
Here's how I'd put it without all of the astrological lingo. Have you ever had one of THOSE mornings? You know when you wake up and things just don't seem to go right. You stub your toe getting out of bed, your car won't start, and you're late to work, and you're sure that today is just going to suck. But later on in the day everything just seems to go smoothly. The day is kind of salvaged, but your joy is brought down a little by how rocky of a start it was. THAT is the kind of situation this chart seems to describe. THAT is the kind of energy you'd be putting into a talisman.
