Feeding my Demonic Servitor

I recently discovered a problem with my Demonic Servitor. He wasn't performing effectively for the purposes I created Him for consistently, but did well in short one-day bursts. I devised an empowering and feeding rite for my Servitor to make Him more effective in a consistent manner. The shape traced in white chalk is a trapezoid, in the center is His Sigil in white chalk and His usual feeding method via a black candle, and His home (An Engraved Amulet) is wrapped around the votive holder. A trapezoid is a shape of angular frustration because of its near but not yet achieved completeness. The shape is perfect for a Servitor because it's existence is tied to providing for us what we created it for, creating a desire to 'do its job' essentially. This particular Servitor of mine is Demonic because of its nature to make me "look better" and feed my ambition through actualization of goals, and my vision of It.

Oh man! Watch that flame rise as you speak. That happens to me in necromancy when I call my working shades up. I'm working it a lot in Vodun with Samedi and the Ghede. It's gotten nothing but results so far. I've worked it from a Norse perspective too. It's awesome.

I'm glad I'm not the only one who saw that! Candles and flames are portals in essence to the realms of dense energy from this more materialistic one. I only know Necromantic knowledge I've learned from reading Somnus Dreadwood and Sorceress Cagliastro, the sorceress being my main working sourcebook for blood magick. It isn't my strong suit in what I know however.

I'm quiet very skeptical to the fact that I came across to a site where someone offering they're services said it's possible to attain a very supernatural powers like fireball, manipulation of weather,and ultimate telekinesis through his very powerful servitor do you believe in this type of servitor that can really bring you an extraordinary power ?

It is technically possible but extremely unlikely that very many of such servitors are created and exist here.
