in a few weeks ill try the summon, first ill start with the easyer spell's...but i have a few questions.
the creeper demon as ii understood is like a demon helper...but with demon helpers you need to droop 3 drops of blood on the demon stone...
how do you reward a Creeper Demon?
with fairy you need to leave an toy/ornament
what do you leave to the creeper?
The only creeper demon summoning spells I've seen on this site were copied off the tv show Charmed "Demons who hide in slivers of night....etc..." so they likely won't work, but maybe it's a different spell your referring to. In the end I'd be careful in casting such spells even if they're legit as it could be risky but that's your choice. What you reward a demon with would depend on what you perceive a demon to be as we all (all som members) perceive them differently. As you mention dropping blood on the demon stone a blood offering/reward comes to mind immediately. As some people perceive demons as beings of energy the risking giving of some of your own energy might be a good reward, but the keyword is risky. Good luck and blessed be.
I cant see how this can end well. Demons can betray you and manipulate you. But, this sounds like a demon that is safer than most. As for rewards, demons feed off negative energy (sorrow, guilt, anger, etc.). Try feeding it negative energy (not too much, or it will become too powerful).
I've never heard of such a thing. Never ever use just one source to research when planning to work with any spiritual being, especially when you're new to the craft.

The Creeper was from the movie Jeepers Creepers and was a very mean entity. BUT totally fiction. However, using such a title could indirectly call on something similar. Not exactly "friendly".
Creeper demon was in Charmed. Again totally fictional. But even in Charmed, again, not friendly.
A name is just a name, but the human mind's association with that name is what matters. None of the sources I saw connected any such being as a "helper". In fact quite the contrary. Please be more careful with your future summoning plans.
Yes, they wont force you to do things against your will (mostly), but they can use VERY powerful temptation, which seems a lot like forcing someone to do something because it can be so strong. They also can mess with your thoughts and thought process.
Your welcome and while being a Christian witch I see demons in a more biblical sense causing me to well fear them at the same time I can see the interest in summoning them and even looked into once myself though I never followed through as the rituals were a bit too large for me to handle then and I didn't have the needed privacy, plus I'm squeamish when it comes to shedding blood but that's my deal. :) I wish you the best in your efforts.
