so Im writing a novel that mainly tells about a war between angel and demon, but I facing some problem along the way and one of it is I kinda confuse how should make the power system here, what kind of power should they have. pls leave ur thought thank youu. xx
I need advice for my novel
Mike5Kilo something like burning things down into ashes.
They can also have something like making their oppenent unable to move by tying them through something
I think that the Demons should have powers like Hellfire or blood/sacrifice based abilities. The ranking system for them could be Lesser Demon, Great Demon, High Demon and maybe even include the 72 demons of Solomon. If you want, there can also be the Devil/the Demon King/Lord.
I don't know what abilities the Angels could have, but their ranking should somewhat mirror the Demon's. There could be Lesser Angel, Great Angel, High Angel, then maybe Archangel. If you were to include a Demon Lord-like figure, them you would also have to have a rival figure.
Well, i think it should start from getting negative thoughts, wrongs not right, did some actions that was never expected, premonitions on what would happen in the next few seconds, minutes, hours, days, weeks, months and years(future) as a child and make sure that this scares his parents and then they get scared of him and let him do as he pleases and have his way. After everything, he kills his parents and goes after whatever he sees and then a certain demon group, approaches him and gives him the power to possess what he wants and in order to serve the demon lord (he will be part of the demon apprentice buh will have a stronger mind and will power that will make the demon lord, find likeness in him and then train him). The angels should have this power of defeating any demon and then be weak physically buh strong spiritually and mentally meaning they should be BRANIACS. Let's say their god was captured by the demon lord and the demon lord sent his demons to the world to win souls for him and then he went to rest, sensing that the Angels cannot do anything that will affect him except only if they find a way in rescuing their god buh totally forgetting that they were BRANIACS, he went to rest. So the Angels laid low and kept their nature hidden, finding ways to release their master
Thank you

Mike5Kilo Hey 
I haven’t read the posts above just skimmed through them. You can find interesting skills and powers from old lores. Pick one piece from the world. I would look into old shamanic stories from Africa. They can give you some solid ideas about the demon powers. As for the angels, you can look up some Greek lore or perhaps Eastern one? Mythology can aid you a lot. 
The reason why I suggest to make a small research is because you might get influenced by novels already written on the topic. Someone mentioned “Hellfire” and such. However, this is too predictable. Not a bad suggestion but will turn the novel into nothing new. Imagine the reader had just finished a story from that genre and bumps into a similar power in your novel. They might mix together the previous work with yours. In regards of supernatural powers, I mean.
That may also lead to the reader comparing your work with the one it reminds him of. 
You can find interesting names for powers and magic in the ancient lores and bend them through your story plot. At least this is what I do.
I believe that a good novel requires at least some research done.
