I thought of that before, but it seems the connection between me and the servitor becomes unstable when I go out.
The way I see it is since the servitor is binded in a physical anchor, it should not be able to go too far from it.
The servitor is not necessarily bound to an object, it can be not bounded too. The essential thing about the servitor is that it is a personal creation. If you forge and program it with a ability to travel, it can travel for certain. There are even practitioners who program their servitors to do tasks independently that are done on a place where they not live themself. They send their Servitor on a travel with strict programming about what the servitor is allowed to do or not. You need give it a strict programming about the job that it has to do and you need a strict programming about how the servitor gets it feeding. So, essentially it boils down to very strict programming and to revision that often enough to keep the servitor stable. The revision of those programs have to be on a regular interval.
To keep things practical you can program a servitor that normally is bind to an object has the ability to travel with you. If you build in the program that you if you perform a little ritual with object, the servitor attaches to you to travel, it is very possible. That little ritual can be as simple as touching it 10 times on a certain places of the object.... I would say, experiment with this. make the next year every 2 weeks a servitor that you program in that way and that you absorb after just ten days. You get skilled in the programming itself after and you are able to refine your methods. It is worth the experimentation. I did this before, just to get skilled in forging a servitor and to see what the effect of programming is. After that period I made servitors that 'lived' a longer period to train myself in the process of revision it. All these servitors were just 'training' servitors for me.
About the interval of revision, that was depended to the original forging and programming. If the original programming was not strict enough, I needed to do more often a revision. If the servitor was acting in the personal space of another person, it needed more often a moment of revision. But that were just short moments of revision. That another person in this case was my hubby who has the hobby of renovating oldtimer cars. I noticed for one car that he needed some assistance. The spare parts had been off the car for so long, that hubby couldn't remember in which order the spares had to be mounted on the car. So I build a servitor that was helping in the visual remembering of that. Hubby didn't know about that servitor. I just gave him the hint to walk to our cupboard with models cars every time before working on his own car. And I presented that to him as just a weekly little precious moment. He accepted the idea to do so and that was every week the very moment when the servitor attached to him, according to the program. He forgot one time to do that, all parts that were mounted in that day had to be unmounted because of forgetting just one tiny part. (poor hubby)
(I see above a little entanglement between spirit and servitor, but that are not the same things, so for the sake of the discussion I would make distinction between both)
