Sigils And Bindrunes Options

I have a problem: I have a servitor that is demanding I need to give it more energy every day are-so, if not it sort of fades. {This may be my fault, in that I'm not fleshing it out enough.} I had the idea that I could use Bind-Runes to fix the energy problem. I was concerned about it taking too much from the Bind-Runs, don’t what it to become more powerful than I can easy dismiss or destroy. However I was unable to find literature on this. I’m open to suggestions.

My apologies for having you type so much of a rant, I should have been clearer. Perhaps "NEED" is a more appropriate word to describe the situation. It needs a lot of energy, it douse not demand.

To give you all a clearer view of my servitor:

Carefully define the intention (to protect me; by alerting me of potentially dangerous physically situations,) as you could imagine this is intended to stay for a wile. Though as a rule for anything over two weeks I prefer a simpler sigil or a spell so I avoid having it lose focus and it has No free will.

As for “littering up the astral” I assure you I am most methodical about such things, for the reason: I don’t like having them hang around needlessly connected to me. When their task is complete they are destroyed. I do hope I elevated you distress.

Now if I understand you correctly Bind-Runes could aid in the definition but can not be used to animate it. Then I still have a problem (and I will state this with care) my servitor needs more energy to stay together that I wish to give it. Is there a problem with my methodology that I'm still missing or is it something ells?

Thanks
