As mad max suggested, use the Rego Corpus guidelines. It is actually quite tricky. I've been thinking about such a power for a talisman, for a Bjornaer (who lacks pockets to bring his talisman with him when in animal form). I've decided it is easier to have a talisman that changes form so that it may be carried more easily by an animal.
The ReCo guideline to teleport self a distance of Arcane Connection is 35...there are lower levels for shorter distances.
So, if you want to teleport the staff a distance of Arcane Connection away to your position, you need an effect which is teleport staff a distance of Arcane Connection away to a location distance Arcane Connection away, so that is a 35 + 4 = 55 Level ReHe effect.
The alternative is to get the staff to teleport itself to you, but then it needs to be triggered somehow --- perhaps by an environmental trigger such as sunrise. This is then a level 35 + 3 levels = 38 Level ReHe effect. The problem is that you can't stop it from occuring, or make it occur at a different time.
Also you need to think about penetration. You need to penetrate the magic resistance of the staff, if you are using a spell to teleport it to you. And it needs to penetrate your magic resistance, if it has an inbuilt power to return to your location. A spell cast by you to get the staff to return to you also needs to penetrate your magic resistance. This is because your talisman inherits your Form magic resistance, even when you are not touching it; but you can only cast Personal Range effects on it when you are touching it --- all effects other than Personal Range need to penetrate. You can suppress your own magic resistance when you use this effect, but that's neither trivial nor particularly safe. You can't supress the staff's magic resistance though.
