Yes. There’s a tut to create servitors I found here: Servitor Creation Engine
I feel like someone posted a free one around here somewhere specifically for helping you developing astral senses, but I can’t find it for the life of me. If your search for “free servitors” there’s a bunch.
Any practice with magick helps you develop anyway, so just working with the servitor is good practice. They won’t be able to replace practice, but they can help you get the most out of it.
